OpenSUSE Install :: Network Speed Slow In OpenSUSE 11.3?
Sep 10, 2010
Does anyone know how to revert network speeds to those attained with openSUSE11.2-64? On openSUSE11.2-64 the reported network download speed was,
max : 420 kB/s
ave : ~ 200 kB/s
After upgrade to openSUSE 11.3-64 the figures dropped to about 25% of the previous values. After upgrade to KDE 4.5 and plasmoid-networkmanagement the initial values did not change but the average value dropped after about 30 seconds to ~ 15 kB/s. Approach so far:
1. The motherboard's (A780GM-LE) build in LAN (Realtek RLT8111DL) was originally detected by openSUSE 11.3 as the Realtek RLT8169 and kernel module r8169 installed. This was replaced by the latest module r8168-8.019.00 from Realtek.
2. After kernel update to Linux 220.127.116.11-0.1-desktop x86_64 the plasmoid-networkmanagement was replace by NetworkManager-kde4. This improved flow with,
What can I do to speed up the start-up after login?
I am running OpenSuse 11.3 with Gnome on my laptop (Acer Travelmate 2490) and I need about two and a half minutes from login until the hard disk lamp 'settles down'. This is much longer than I have been used to expect from earlier OpenSus versions. Are there some default applications/processes I could ditch?
I'm new to openSUSE and my computer is quite slow although my computer isn't that bad. I opened up ksysguard and it appears that my CPU is the bottleneck. My CPU usage is usually 100%, then after a few seconds, it goes down to 20-60% and then it goes back up to 100% after another few seconds. It says I have 141 processes running (I don't know if that's normal or not).
My Specs are: CPU: AMD Duron (tm) processor 1.8GHz Graphics Card: NVIDIA GeForce 6200 Memory: 2GB RAM I'm using KDE.
I have recently installed OpenSUSE 11.3. I can play audio files, but there is a problem recording, namely the recording is way too slow. This was tried 3 ways: in Audacity, in Skype (making a test call), and using the arecord command in a console, as root. To make the playback sound normal, I tried taking the already-recorded file and speeding it up in Audacity. It was necessary to speed up the recording by 50%. I've tried updating alsa and other suggestions which I could figure out, and run the scripts for diagnostic information. BTW, I'm using a headset plugged in to standard 1/8 inch mic and speaker jacks, not a USB headset.
For some reason Firefox loads pages really slow on my 11.3 install. Chrome everything loads fast. I am running the latest of firefox.I have done the usual tweaks to the about:config that I found on the internet. Is there a reason for this and can I fix it?
Is there any method of selecting a network speed on my set up? It is capable of running at 100mb/sec but have the feeling that it isn't. Plug in vista on a lap top and no problems at all. It's also noticeably quicker. I assume that a straight install does set up bi directional and 100mb/sec?
I'm facing an odd problem with a fresh install of OpenSuse 11.4 on a Dell PE-2950, using NIC Broadcom BCM5708C (rev 12) NetXtream II. Driver's are up to date. I'd installed vsftpd and configure it. I can connect from anywhere in the network where I setup this Server. The odd problem is that when I'm sending a big file (5.5 GiB for example), from another PE-2950 server (Windows Server 2003 64 bits R2) with another BCM5708C nic, the speed of the transfer starts at 90 MiB/s approx. but after 30 seconds , it drops to 15 MiB/s and never raise again. Driver's are up to date too.
However, from another Server in the network, a Dell R710 with SLES 10 SP3, the transfer speed is at 90-100-110 MiB/s all the time. The switch is a HP Procurve 2910al-24G, with all ports at gigabit speed. I'd tried with different FTP clients in Windows: WinSCP and the Windows's ftp client, but the result is the same: speed falls down after 30 seconds approx. using the Windows-Box.
I was a user of openSUSE 10.3. I used to get a decent speed in BitTorrent (using KTorrent 2.2.1) there, since I had earlier used Windows and the speed wasn't as good, even in Windows 7. Recently, I installed openSUSE 11.2 and found that I wasn't getting the good speeds in KTorrent. The overall performance was a fraction of what I used to get in the older Linux installation.
I decided to verify whether my suspicions were justified by again reinstalling openSUSE 10.3. When I did this, I was again able to get the great performance I used to get always with openSUSE 10.3 running KTorrent 2.2.1 I don't know what causes this, but I know that this sad thing really has happened. A newer version is actually not worth it! I hope my voice reaches the openSUSE developers and such bad incidences don't occur anymore.
I have an 1TB hard drive, half of it for Windows XP SP3, another half for OpenSUSE 11.4. After installing OpenSUSE, it didn't take me much time to notice that there was something wrong with KDE: sometimes it loaded quite fast, as expected, but most of the time I'd have to wait around 1 minute in that loading screen. Then I updated the kernel, as well as KDE itself, but that didn't solve the problem.
After that I tried to start the system using Enlightnment, and it was lightning fast compared to KDE, however, I didn't quite like its interface, and for some reason GNOME refused to start. All that was too frustrating to me, so I gave up and have been using Windows for the last few weeks. Got sick of it now and here I am on OpenSUSE again. Oh, it feels sooo much better! BUT, I'm still with the same problem.
My specs are as follow: Motherboard: Gigabyte MA78GM-S2H (with updated BIOS, version F11) Processor: AMD Phenom X3 8450 Memory: 2GB Videocard: Nvidia Geforce 8500GT (using NVIDIA proprietary drivers) OpenSUSE 11.4 KDE 4.6.0 Did I forget anything important?
Ps.: I didn't have these problems with Mandriva 2010.2, which, if I'm correct, used the same KDE version.
I have a Dell inspiron 640m (1405). I am a reasonably clued in linux user, but I am getting serious networking speed problems. The networking card is an intel 3945ABG When wirelessly connecting with windows XP, everything runs fine and the network connection is fast.
When connecting with any linux distro, the networking speed is abysmally slow, and the connection drops randomly. (the network is recognised and the connection is made however)
I have just formated and did a fresh install to start all over. I installed Ubuntu 9.1 and everything went fine but the network. The computer serve as a NAS and MediaPlayer. When getting a file from the server, I get a speed of 40-60mb/sec, which are good for a Gigabit network. When I try to put a file in, the speed can't pass more than 1mb/sec and often stop.
I have the problems with transfer speed between samba and Windows XP clients.
Samba server configuration: Quad Core 6600 CPU. 4 Gb RAM OpenSUSE 11.2 with kernel "18.104.22.168-0.1-desktop" Samba - samba-3.5.1-1.1.i586 Test: 4 GB File copying. One file.
Transfer speed from Samba Server to Windows 7 and XP clients: (Windows clients copy file from Server share -> to local drive) From Server to Windows 7 client 1: 85-90 Mb/sec From Server to Windows 7 client 2: 90-100 Mb/sec From Server to XP1 client 3 75-100 Mb/sec
Transfer speed from Windows 7 and XP clients TO Samba Server: (client copy file from local drive -> to server Share) From Server to Windows 7 client 1: 12-20 Mb/sec From Server to Windows 7 client 2: 30-35 Mb/sec From Server to Windows XP client 1 20-27 Mb/sec

I have very slow write speed when copying file from Windows clients to Samba Share. Samba speed is slower than Windows native clients connections ?
In mi fstab file I mount a smb file server at boot. The code is: //<ip address>/data /home/eng-2/NAS smbfs credentials=/home/eng-2/.smbcredentials,dir_mode=0775,gid=1000,uid=1000 0 0 Transfer rate to the server is approx 100 KB/s Whilst transfer rate from the server 16 MB/s If I mount it from Places>connect to server. Both to and from speeds are 16 MB/s. Why is it so slow when mounted through fstab?
I'm experiencing very slow network speeds in one direction (out) on a clean install of debian.

I've tried with different cables on the server, no luck. Also note that the laptop gets full speed to speedtest.net as per my internet subscription (75/75 gbit fiber), so the laptop can be ruled out as a problem since it gets more than 75X performance to the internet compared to the local server.
The main purpose of this server is to be a virtualbox host. I've set up one guest system and ran iperf between the host/guest (bridged network). It gives better numbers, still the host -> guest direction is much slower than it should be:

I have problems with my network speed when i ping my proxy server I end up getting a high packet loss generally more than 30%.I have tried to use various network monitoring softwares like etherape, wireshark, tcpdump but I am not able to get to the bottom of the problem.basically I am trying to find out where the lost packets are going.
A lot of people have the problem to find themselves with Lucid Lynx 10.04 and experience massive issues when connecting to wireless - me too. As a service, here some relevant links which promise relief:
I tried all of them, and none reliably worked. Every solution which required re-association wtih the AP helped for some time, but nothing helped for long. First, don't let yourself fool by the disable IPv6 trap - while it is "enabled" it is acutally not used by Lucid! I have a clean install of Kubuntu 10.04 on an AMD64 Laptop with Broadcom STA driver: 03:00.0 Network controller: Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03) However I can reliably stabilize my connection for some time either by manually disabling WiFi with the hardware switch or disabling WiFi by software means and re-activating. This brings speed at par with Kubuntu 9.10 until some time. Can anybody confirm this behaviour?
I'm installing opensuse 11.2 x64 on my machine.I have win7 installation so I'm making it dual boot.The problem is that the installation is extremely slow. I've started it 20 min ago and it is still at 3% in preparing disks part of the setup.The installation is standard (no shrinking or etc) - I'm installing it on a separate empty partition on my raid volume.
My laptop is configured to boot openSUSE 11.1, Vista, and Win2k. Access Point is AirLink101 (Atheros Based).Laptop is Acer Aspire 9410-2028.Win2k wireless speed is 108 (using Atheros Drivers)Vista Wireless speed is 54 (using windows drivers)openSUSE 11.1 Wireless speed is 12 (Using MadWiFi)When I was on 10.3 it ran at 108 on 11.0 it was 36. 36 is not 108 but it was solid 36. I tried using networkmanager and speed went down to 1. Each new version of openSUSE has caused a drop in wireless speed.lspci |grep Atheros0a:05.0 Ethernet controller: Atheros Communications Inc.

I have a Ralink rt2870 chip. Since it did not work with 11.2 out of the box (should it not be in the kernel?), I had to install this driver from the software search area on opensuse.org:
After installing it, it works, but only at reduced speed, (I think), because when keeping the mouse over the list item (of that connection) in Network Manager, a window pops up saying I only have 54Mbit/s.
It says: Type: WiFI Interface: ra Hardware adress: 00:15: ..... Driver: usb Status: connected Bit rate: 54 Mbit/s

write speed: 80-90-100 MB/s read speed extremely slow: 3-4-5 MB/s (really funny - our administrator shoked, but i'm not fun, i need fast lan for work)But when i reboot to windows 7 - i have 60-70-80 MB/s in both directions. Read and Write - nice.What happened? kernel updated and all last updates is applied (exclude kopete-because i use old kopete with animated tray icon).I have to tried many tunes like: "noatime" "directio" and also in /etc/modprobe.d - put conf file with: options cifs CIFSMaxBufSize=130048
I'm having very strange issues with OpenSUSE 11.3 KDE LiveCD, mainly performance-wise. Most noticeably, it takes 10-30 minutes to actually boot the system, and it doesn't matter whether the LiveCD is booted from the USB or if it's install into the hard disk. There aren't any noticeable errors during boot, though, except a few "timeout" errors and not being able to lauch VirtualBox Guest Additions (which I don't need since it's not run from VirtualBox anyway).
It takes the most time during the "scanning USB devices" section if I boot from the USB, and during the state where it detects the network card/assigns an IP. In both cases, every dot that appears there takes around 2 minutes. During the boot, the PC seems to be mostly idle, and appears to do something only occasinally, when certain parts of the boot sequence are passed, so that makes boot up feel "jumpy" - nothing happens for 10 minutes, then the PC starts accessing the HDD, then nothing happens for 10 more minutes.
There are other performance problems, noticeably during installation to HDD (through the Install option from the CD startup menu - it's quite a bit faster when started from the running LiveCD). For instance, it takes around 5-10 minutes to make the screen where you need to choose the language and keyboard layout responsive. The performance, in both cases, seems to be inconsistent - sometimes it starts booting and responding quickly, the other times it's really slow, up to the point of outright hanging.

Are there any easy special tricks to speed up the boot time?Coming from Linux Mint (GNOME), I could get to the Desktop from cold in less than 25 secs.Now in openSuse 11.3 (KDE4.5) it takes more than twice that.Is this a function of KDE or have Ubuntu done something that openSuse hasn't to speed up the boot?
I used command as followings. nothing special. mount -t cifs //192.168.55.53/windows$/Home /mnt/ -o user=username%password It works well after mounted. But mounting itself takes 1-2 minutes terribly. After mounted successfully, file transfer speed looks to be normal.
I have recently moved countries and have finally got my internet connected today after a lengthy wait. I have a pretty fast connection - it's a fibre connection at approx 100Mbps Between my onu (modem) & computer (Lenovo SL510) I have a cisco wrt120N wireless router. I'm using Opensuse 11.3 (also dual boot with Win7)
My problem is . . . When I enter url in firefox (4) I get the message "looking up www. . ." for approx 5 to 15 seconds before anything starts to load. I also have the same behaviour in konqueror, firefox and yast software manager.
If I use Google Chrome the pages load instantly. Even never before visited pages.
A typical webpage such as Stuff.co.nz - Latest New Zealand News & World News, Sports News & NZ Weather Forecasts takes approx 20 to thirty secs to load in firefox and 3 seconds in Chrome. I can see the same behaviour always whether Chrome used first or firefox used first - so cache does not appear to be the issue.
If I boot into Win7 - websites load instantly there also.
I have updated to the latest wireless drivers for my system - but the behaviour is also evident if I attach a lan cable.
Here is a little info

I've recently installed openSUSE 11.4 (64 bit) on my system and am experiencing severe performance issues with websites using https (any site using https). Page loads over https take anywhere between 30 seconds to 2 minutes. It's the same issue posted here Secure sites load slow or not at all -- there was no confirmed solution.
- My router/hardware configuration has not changed in a long time and I've run Ubuntu, Arch Linux, and Windows XP on the same machine within the last year and have not had any issues. - I also have a laptop running Arch Linux (kernel 2.6.38) and this problem does not occur using Firefox 4 or Chrome. To add to the madness this problem occurs while running Firefox 4 inside a Windows 7 guest via virtual box, but NOT while running IE 8 inside the same guest. - This issue occurs using Firefox 4, Chromium, Opera, Konqueror, and Arora. - I've disabled ipv6 in Firefox via about:config. - I've disabled ipv6 in yast and have attempted to use both the "ifup" and "networkmanager" options. - I am not using a proxy server. - I've attempted the fix posted in the Ubuntu forums for a similar problem [ubuntu] [SOLVED] Banking Site is very slow.
Each time I boot my opensuse 11.2 system one of the very first things that happens is that the system seems to test how fast it can handle my HDD, an older EIDE drive with the wide ribbon cable. This takes about a minute, one test each 15 secs or so until it gets down to about 33 speed and then the boot proceeds as normal.
I guess this is just the normal testing by the more advanced sata procedures in the kernel (2.6.34). If I were only booting this machine once every 6 months it would not be an issue, but I do so at least once a day. Is there any way to indicate to the system the speed of the connection so that it does not have to do the test, or close the gap a bit so that it finds the answer more quickly?
I'm running 11.2 on a Dell Latitude D630. Everything has been great other than issues with Suspend and hibernate not working correctly. However after about a month of use browsing the web has really slowed down bad. It doesn't seem to matter if it's in Firefox or Chrome either. I am using a wireless connection that is getting the signal at 85-95%. Even though I still tried using a direct cat-5 connection to the router and it was still slow as well. I have the fastest broadband connection my cable offers and my windows boxes on the same network are still flying.
Recently I purchased a new laptop and installed openSUSE 11.3 x64 Gnome. I was running openSUSE 11.2 x86 Gnome on my previous laptop. Most things are working well, although still tweaking things here and there.
The biggest issue at the moment is starting the network. When I boot the system it loads into desktop (gnome) no problem, but then takes between 3 - 5 minutes to come up asking for Default Keyring Password before it will launch network manager. Everything else has loaded and it running fine except the network.
The first time I launched the system (after install) it worked perfectly, however soon as a set the password for the Default Key this started happening. The time delay before it launches does vary each time but always around 3 minute mark.
