Debian Configuration :: When Install NIS / System Becomes Very Slow

Apr 12, 2016

I have installed jessie on a couple of machines. One is configured as the NFS filesystem exporter and NIS server. The other one, I am trying to configure as NFS and NIS client. NFS does not seem too much of a problem, I can mount the exported filesystem to a directory in the client and unmount it, but when I install NIS the system becomes very slow. Any command preceded by "sudo" takes a very long time (a few minutes) to complete. Then, upon rebooting the system, it reports many services failed to start (login, accounts, modem manager, avahi, network manager, exim). When if finally completes, I get a terminal login, instead the graphic login window.

Debian Configuration :: System Running Is Very Slow

Oct 28, 2010

I'm running testing and over the last week or two my system is getting slow. Any disk access slows everything to a crawl. Even the cli can take several seconds to display characters as I type them.

Debian :: New Install Running Slow - System Freezes Every 30 Seconds Or So

Sep 26, 2015

So i just finally installed Debian Jessie OS, replacing Ubuntu. But now it is running extremely slow. It's not internet connection. The internet speed is running fine (Videos load quickly), but it's like the system freezes every 30 seconds or so. A video can be fully loaded but still stops and starts constantly. Just browsing the internet, or non-internet things do the same also. I switched back to Ubuntu to see if it was different on there, but Ubuntu is running fine.

Debian Configuration :: Wlan Really Slow Under Lenny

Jan 10, 2010

i use a telekom s100 set-top-box, which originally had a prism54 wlan-card. but wlan was very slow. but the driver was working well and it did not seem to be a configuration issue, so i assumed that its that card which is so slow. following i purchased a atheros based wlan-card which is working perfectly well with the ath5k driver of my linux kernel (2.6.26-1-686). but the connection is pretty bad anyway. i get max 300kb/s from pc to pc. as its the same with 3 different cards i tested in the s100 i assume it is a configuration issue? or might there be chipset or mini-pci-slot limitation?

when i check the connection with iwconfig the bitrate is somewhere between 1-54mb/s, rising to 54mb/s and then falls back to 1mb/s, rising to 54mb/s again, falling down, its an infinite loop. im using wpa_supplicant for the connection, but i don't think thats the malefactor. well, you never know .. i tried to set the bitrate with iwconfig wlan0 rate 54M but that ended in a disconnection ...

Debian Configuration :: Graphic Slow After Kernel Upgrade From 3.16 To 4.1

Sep 24, 2015

Intel Core i7-5500U with Intel HD Graphics.So I updated to the backports kernel and backports intel xorg drivers and I have the weirdest thing.Everything is stuttery even cinnamon desktop effects are no longer smooth. If I boot back to 3.16, everything is butter (except the screen corruption). Even my favorite wine game dropped 25% in fps.

I remember that on windows, if the cpu is too slow (pstate_min_speed), graphics is also stuttery. However, increasing /sys/devices/system/cpu /intel_ pstate/min_perf_pct even to 100% didn't do the trick. I suspect, that this measure is causing it: URL....

how to increase the performance again? I just found out, after running glxgears (with about 40 fps), that xrandr shows an available framerate of 40fps

xrandr
Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
eDP1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 293mm x 165mm
1920x1080 60.00*+ 59.93 40.00

I guess that's what makes it feel slow. Do you know how to get that back up to 60 (fixed)? It seems like the screen refresh rate set in xrandr has no effect on the problem. When I boot, glxgears runs with 60 fps and everything is fine. After a while, it drops to 40 and the whole desktop keeps stuttering. if I change the resolution with xrandr and then change it back, it goes to 60 again for a while

LVDS_DOWNCLOCK is disabled

Debian Configuration :: Access And Connecting To SAMBA Are Too Slow

Mar 29, 2016

Let me introduce myself, my name is Carlos Alegría from Chile and I'm System administrator for a educational Institute. We use samba+ldap, for login accounts and file sharing but we not use samba with PDC.

Long time ago at the 2009 year, I was Installing the same system and this worked perfectly. But on our summer the hard disk of server has broken, so i was need installing all the system again. So the problem is with SAMBA, when i connect to the network resource, this is to slow, and when i try transfer files are slow.

My sistem is on Debian 8 Jessie and the Samba Version is 2:4.1.17+dfsg-2+deb

Code: Select all[global]
   workgroup = LABORATORIO
   netbios name = Shinigami
   server string = debian

Debian Configuration :: Deconfiguring Network Devices Is Slow

Jan 26, 2010

I've been keeping my feet wet learning Debian. So far only in a virtual machine but I have had that machine running every day. I'm running a Lenny/Squeeze mix.The system is running well, yet every time I reboot or halt the system there is a long pause at the "Deconfiguring network devices" message. I traced the message to S35networking. With this virtual machine, which is a model for my eventual physical machine installation, I have only a single wired eth0 NIC (pcnet32).

I'll take a wild guess the script might be trying to find additional cards to halt, or perhaps a wireless card that does not exist, but that is just a guess. I'm stil learning my way around with how the init.d scripts and various /etc config files interact.I'm using a static IP address. DHCP is disabled, as far as I can tell. I did not notice anything in the logs.

Debian Configuration :: Seeing Slow Network Performance With Large Mtu?

Apr 22, 2010

I have 2 ASUS Boxes (one with 8GB, one with 4GB) When both mtus are set at 7200, using scp to copy a 56MB file takes 2:06. If I reduce either mtu to 1500, the speed is 2 seconds. I'm wondering if this is some kind of kernel bug or driver bug or what. For the moment, I've lowered the mtu to 1500 to get the performance out of the machines, but find it interesting that what should make it faster is actually slowing down. Where should I post this to get it looked at? Is anyone else seeing it.I see a similar performance issue with smbclient too.

Debian Configuration :: Torrent Traffic Very Slow / Make It Up?

Jul 10, 2011

I am running on debian squeeze 6.0.2. I have been using it for the last id say 3 weeks and really am enjoying it.

I generally use transmission-gtk to share files over the internet. Normally I seed torrents at 110-160kb/s for hours at a time. However after messing around with firestarter my upload speed for seeding torrents rarely peaks over 70kb/s. I have purged firestarter with no success of my regular upload speed, and am very confused as to what happened. I also notice sometimes when it will get to about 70kb/s it will immediately drop down to the 20-30kb/s range.

For incoming bittorrent connections I use port 37294. I have set port 37294 to be allowed in my firewall, and forwarded in my router (since purging firestarter did not help I just reinstalled it).

I have also read allowing ports 6881-6889 is important, but I have never done that in my history of using torrents, and I have never experienced a decrease in UL speed like this.

Have I done something incorrect? I have never had this issue on other machines?

Debian Configuration :: No Longer Allowed To Access The System Configuration

Jul 31, 2011

I am using Squessze and Gnome. When I try to use the gui System>Administration>Network or Users and Groups I get the error The configuration could not be loaded. You are not allowed to access the system configuration.Everything was working before. I read around a bit. In some cases,it was caused by mismatching group and password files after using the gui. I do not know how to check if they are matching. Of course I do not know for sure that is the problem in my case.

Debian Configuration :: Direct Ethernet Rsync To NAS Very Slow (74kbits)

Jan 30, 2016

So I have a GoFlex NAS driver, which according the specs has a theoretical maximum performance of 100 MB [URL] .....

I connected by ehternet to my PC (GNU/Linux, Debian 8 ) to do a backup.

I mounted it with cifs:

Code: Select allmount -t cifs "//goflexhome.local/GoFlex Home Personal" /mnt/gf/per/ -o credentials=/root/gfpass,uid=1000,gid=1000

And then tried rsyncing my home folder.

Code:

Select allDIR=/home
BACKUP_FILE=/mnt/gf/per/bck2016/

FLAGS=" --archive --one-file-system --acls --xattrs --numeric-ids --fake-super --progress  --human-readable --ignore-existing --log-file="backup.log" "                                                                                                                 

FLAGS+=" ${DIRS} ${BACKUP_FILE}"

rsync ${FLAGS}   

I then used iptraf to check the performance and I get miserable results (from the PC), even below 1 MB:

total 74.7 kbits

Debian Configuration :: Squeeze Installed - Slow Responses To Ping

Debian Configuration :: Slow And Laggy Network With AR5008 (Ath9k) - XP Okay

Mar 4, 2011

I got a TP-Link WN951N Wireless-N PCI card for my Squeeze HTPC (this is AR5008. Performance is awful. On the lucky runs I'm getting 4 MB/s from Samba, most of the times I'm seeing 1-2 MB/s, and sometimes less than 1 MB/s. Also, ssh is not smooth, e.g. when I type commands, it can take seconds before text appears on the console, or I get slo-mo. Forcing 11g gets me a consistent 2.2 MB/s but lag is still there.

The machine has also been tested under XP SP3 and pulled off a solid 11 MB/s on a large file with no lag, so the hardware would seem OK. I've tried several kernel versions (both Liquorix and Debian stock), and a couple versions of compat-wireless (2.6.38-rc4 and 2011/03/03 bleeding edge), with little variation in outcomes. The logs got no weird messages in them, although with the more recent drivers/kernels iwconfig looks like this:

wlan0
IEEE 802.11bgn ESSID:"GuessIt"
Mode:Managed Frequency:2.457 GHz Access Point: x:y:z:t:u:w

Tx discarded packets are through the roof and excessive retries is not bad either. The system doesn't run NetworkManager, wicd or whatnot. All of the wireless is configured through /etc/network/interfaces:
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface

Did I commit some horribly naive mistake or overlook something Really Important(tm) ?

Debian Configuration :: Slow Boot Waiting For DHCP On Wire?

Mar 23, 2011

Up until very recently I've had a wired network, and at boot I'd see messages about DHCPREQUEST and DHCPOFFER and stuff as it set up the wired network.

Now I've just got wireless working instead, but it still tries to use DHCP on the no-longer-existing wired network. So it says "DHCPDISCOVER on eth0..." and waits for a bit, then again and waits again, and all the time the boot is waiting for a reply to its DHCP requests and it's not going to get one. It doesn't seem to do any harm, because once it's given up and proceeded with the boot then the wireless does seem to work fine, but I'd like to speed up the boot a little by cutting out this needless waiting. Has anyone got an idea how I can stop it? I tried in Preferences-Network connections and in Administration-Network, and in System Tools-Network tools, and also from the network icon in the task bar, but I can't find anything which lets me configure the wired network eth0 or disable it or disable the DHCP.

Debian Configuration :: Wheezy Xfce 4.8 VERY SLOW First Thunar Startup

May 16, 2011

I upgraded my main PC's Xfce 4.6 to Xfce 4.8 this morning.Now, every time I start Thunar for the first time after a new boot, it takes about 30 seconds to appear, and then about 10 seconds later, a second instance of it appears.After that, Thunar appears instantly every time I start it during that same session. But if I shut-down or restart my PC, Thunar again takes about 30 seconds to start up, and a second instance of it appears about 10 seconds later.

Google searches seem to indicate that people running other distros are also experiencing this problem. On advice in a different forum, I deleted the ~/.config/Thunar folder and restarted my PC, but that didn't help -- it created a new Thunar folder, but the long delay and the double-Thunars are still there every time I run Thunar for the first time in a session.

Debian Configuration :: Slow Custom Kernel Build Amd64

Aug 17, 2011

I used make-kpkg to build the 3.0.0 source debian wheezy on a dual 3.4GHz Xeon/L1-16k/L2-1mb/800Mhz bus with 4GB PC2-3200 ECC ram and Ultra 320 SCSI, using CONCURRENCY_LEVEL=4 (2 hyperthreading cpus=4 cores). The build was slower than molasses in January! Top reported cpu usage total between 10% and 25%. Why won't the build use the amount of machine it has available. One footnote: I wasn't using swap space. It literally took over an hour to build the deb kernel package.

My notebook from 2003 is at least three times faster building the 3.0.0 debian kernel source. Is it possible that this might cause improvement: make -j4 KDEB_PKGVERSION=version deb-pkg

over

CONCURRENCY_LEVEL=4 make-kpkg --initrd --revision=123x kernel_image?

Could amd64 vs. i386 have some influence? Could the small processor caches on the XEON cpus have an effect. The 64-bit machine absolutely flies doing everything else. I'm miffed! I've used debian since woody, although I am not an expert, but I'm no slouch!

Debian Configuration :: Extremely Slow Transfer Rate On Flash Disk ?

Jul 12, 2011

Same computer and flash. Two results on different OS:

Write speed under debian: 0.4 MB/s

Write speed under Windows: 6.6 MB/s

From what i've been reading on the net I guess it's something to do with the mount - sync option.

I've notice that there are couple of workarounds but all of them are pretty tedious.

Is there any simple (GUI - one/two clicks) tool that allow to mount/unmount flash disk easily using the correct options?

I'm using Squeeze 6.0.2 (Kernel 2.6.32-5-amd64), gnome 2.30.2

Debian Configuration :: Slow Transfer Speeds On SAMBA Share But Gigabit Speed On SCP

Feb 12, 2016

I'm having a strange problem with data transfers between systems. I have a file server + my desktop. Both are running Debian 8.3. I have a samba share running on the file server and I mount the shares on my desktop on boot via /etc/fstab

When I copy a file using the nautilus from my home folder (on my HDD) on my desktop to the mounted network location, my transfers start out at gigabit speeds 80MB/s-90MB/s for a couple seconds and then drop down to about 8MB/s

But when I terminate the transfer and then use scp to transfer the same file, I get consistent gigabit speed throughout the transfer. I am not sure what is going on.

Debian :: System Slow After Successful Hibernation Cycle

Feb 2, 2010

I'm running Debian Sid amd64 on a Vostro 1320. Both hibernate and suspend works fine using the kernel hooks, but after the system resumes from hibernation, it starts to get really sluggish. Iceweasel hits 100% CPU use, and I have to close it and open it again to get it working, and generally the system is just must slower than before the hibernation. I have to reboot to get performance back, and even doing swapoff and swapon does not solve the problem.

OpenSUSE Install :: Installation And System Really Slow

Apr 17, 2011

I've some problem with openSUSE 64bits and more precisely extreme slowness.

At first, it was during the Installation (net install), each action (click on a button for example) was followed by a global freeze (though mouse was not). The entire configuration (the first part of installation) took me about 1 hour... At that time, i was thinking "ok it's just installation, it will be fast and smooth in the end..."

I was wrong, the system is as slow as the installation but weird thing: it's only when I log on that the system slow down. I mean the booting process doesn't seem slow and I've not seen any errors. So what's going on ?

I don't know if it's the cause or the consequence but i noticed that my cpu was always at 90+ % except when I don't do anything (useful isn't it?) so it may be because the system doesn't manage my cpu the right way. (it's just an hypothesis)

Now configuration information:

Software:

I tried to install openSUSE 11.4 64bits with the net install downloaded yesterday from the official website. I chose Gnome. I don't have swap (see hardware below) and I have a different partition for / and /home

Kernel: 2.6.37.1-1.2-desktop

Hardware:
Asus X5BVN laptop
Intel Core 2 Duo P7350 @2GHz
4GB DDR2 RAM (enough ram -> no swap)
nVidia GT240M 1GB
Intel WiFi Link 5100
Atheros AR8131 Gigabit Ethernet (odd thing: during the installation it wasn't this name)

Debian Configuration :: Install A Multi-core System And Configure It To Run Several VMs, One Each For A Firewall, A Caching Proxy Server, A Mail Server, A Web Server?

Jan 25, 2011

I will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.

In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).

Ubuntu :: USB Disk - Slow Transfer Speeds And Slow System?

Apr 17, 2011

Whenever I transfer a movie into my 16GB USB flash disk, my whole system becomes windows-like and unusable!

When i drag the file(s) into the USB disk folder, it starts out fine and pretty darn fast (25mb/sec) then slowly decreases until it's unbearably slow (3m/sec) and as a side effect my whole system starts deteriorating. I basically have to wait for the file to finish transferring before i can use my desktop again!

This has been happening with every version since Karmic (all 64bit)- I put up with it because I don't use the USB stick that much.. but lately it's been my go to source for transfering large files to/from work.
