Ubuntu Servers :: Samba Configuration - File Transfers Between The Machines Are Extremely Slow

Nov 1, 2010

1. When I'm not logged into the server, only the shares are visible on my Windows computer. Clicking on the share folder displays an error message. As soon as I log in at the server, the files within the shares become accessible on the Windows box.

2. File transfers between the machines are extremely slow. Watching the system monitor, there's a brief burst of network activity followed by 10-30 seconds of nothing...on a gigabit network, the effective transfer rate is ~120kbs. There's no other network activity going on that would account for this behavior.

Networking :: Slow File Transfers Using Samba?

Feb 2, 2010

I am running Samba on a debian Lenny box on a wireless home network. I find that file transfers to the samba share are very slow. It takes over a minute to copy a 40MB file to the linux box, but only 20 seconds to copy the same file to a windows XP box on the same network.

Anyways, I could use a little direction on how to proceed with this, I'm really not sure where to start,

Ubuntu :: Slow File Transfers On 10.10?

Oct 30, 2010

Has anyone else noticed that file transfers on Maverick are significantly slower than on Lucid? A review of Maverick on Tom's Hardware finds that it is considerably slower. My own test says: On 10.10, file copy between two NTFS drives maxes at 30 MBytes/s; on 10.04.1, the same operations clock in at 40 MBytes/s. Both drives are capable of rw speeds of 70-90 MBytes/s, which I got on WinXP, and hdparm's cached read results back that up.

why file transfers are so slow, and especially why Maverick is even slower than Lucid?

Fedora :: File Transfers (cp, Mv And Rsync) Slow System Tremendously

Aug 24, 2011

When ever I transfer large files using cp, mv, rsync or dolphin the system will slow down to the point that it's unusable. It will sometime hang completely and not accept any input until the file is transferred. I have no clue what could be causing this problem but I know it shouldn't be happening.I am using Fedora 15 (2.6.40.3-0.fc15.x86_64) with KDE 4.6. have a Phenom II 955 processor, 6 GB of system ram and the OS and swap file is on an 80 GB SSD. Copying files in the SSD doesn't cause any problem, but moving files between my other two large HDDs causes the extreme slow down. Using htop I can see that my system load jumps to between 3 and 4, but my RAM and CPU usage stays low during the transfer. Here are two commands that take about 10 mins to run and make the system unusable while it's running. It usually transferring around 2-20GB worth of data during the transfers:

cp -a /media/data.1.5/backup/Minecraft/backups/* /media/data.0.5/backup/Minecraft/backups/
rsync -a /media/data.1.5/backup/ /media/data.0.5/backup/
/media/data.1.5/ is the mount point for a 1.5 TB internal SATA drive, and /media/data.0.5/ is the mount point for a 500 GB internal SATA drive.

Ubuntu Servers :: MySQL Extremely Slow

Jan 27, 2011

I've got Ubuntu Server 10.04 on a fairly beefy box (quad-core xeon 2.67ghz, 2gb ram) Standard mysql-server installed, with many databases.Lately, mysql has been extremely slow and almost non-responsive. Server loads are low.Running mtop reveals many, many processes from the user: debian-sys-maint querying the information_schema table with the exact same query, over and over."Select count(*) from tables where engine = 'innodb'"

This is adversely affecting my database server, and thus my websites which rely on mysql. Every search I've done looking for more information about the debian-sys-maint user shows problems where that users was deleted. The user isn't deleted.

Ubuntu Networking :: Slow File Transfers (FTP, SCP) With Intel Gigabit Or Atheros WLAN?

Nov 16, 2010

I just installed ubuntu as my primary OS, but I have the disk with XP on it and I don't want to go back, but I need faster network connectivity. I have a T60p with Intel Gigabit jacked into my Gigabit router which also has my desktop (running XP) and my NAS. If I FTP files from my NAS (or SCP), I get transfer speeds around 250-500 KB/s (which is not very fast). On this same switch, from my XP desktop I get transfer speeds around 12 MB/s. I get the same speeds using my 802.11n card (Atheros) as with the ethernet NIC (250-500 KB/s).The drivers for the ethernet card and the atheros card are e1000e and ath9k respectively.I have disabled IPv6. Since the problem occurs using either interface, I am just going to concentrate on fixing it for the Ethernet interface (since I believe it to be a systemwide problem).

Code:

skinnersbane@albert:~$ sudo ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full

[code]....

Clearly my card is running at Gigabit, but why the bad transfer speeds? I am using filezilla for FTP (technically FTPES). I closed every other program. My CPU utilization does seem high and I wonder if this is part of the problem. I had no problems with throughput using either interface in Windows XP just one week ago.

Debian Configuration :: Reboot Both The Server And The Client Machines Every Time Change The SAMBA Configuration?

Apr 5, 2010

I am *finally* getting around to rebuilding my file-sharing computer. I'll be sharing files with both Linux and Windoze machines. It's a home network, so there's nothing fancy needed. I know I have to tweak my smb.conf file until I'm satisfied with the features and security. I'm using SWAT and I'm starting with a bare-bones conf file. It's not secure but I can see the server and selected files/directories from my other Linux box.

My really dumb question is, do I have to reboot both the server and the client machines every time I change the SAMBA configuration? I thought I just had to stop and restart the SAMBA service in the SWAT software - but then the server disappears from my client. It looks like I need to reboot both machines for the client to see the server.

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

Ubuntu Servers :: Dovecot - Outlook - POP3 - Extremely Slow Receiving?

Jul 11, 2011

recently I've replaced an old windows mailserver with a new one running 10.04 LTS (postfix - dovecot) but I got a strange problem with MS Outlook 2003 and 2007 on Win XP. These MUAs receive new messages extremely slow. Some of messages are received repeatedly. All I found in /var/log/mail.log is login and then (after 1 minute) disconnection for inactivity. No errors.:

Jul 11 10:36:51 dovecot: pop3-login: Login: user=(user@domain.org), method=NTLM, rip=xxx.xxx.xxx.xxx, lip=xxx.xxx.xxx.xxx Jul 11 10:37:07 dovecot: POP3(user@domain.org): Disconnected for inactivity top=0/0, retr=1/5434, del=0/12, size=954793 nothing more. And outlooks wait and wait reporting "receiving". What they are waiting for? Is there something dovecot should send them?

At the same time Mozilla Thunderbird and Opera Mail on the same network with the same setup don't have any problems. I just don't get it. Does anyone know what to do to get it work please?

Ubuntu Servers :: Lucid Slow Throughput To Windows Machines

Jun 16, 2010

Having finally got Samba shares and printer shares working on my Lucid Lynx server, I've noticed that the throughput from/to those shares is very slow to what I was used to when I had those shares on a W2K server.Having Googled this problem, I noted that there was a known issue with this in Karmic (believe Brian Wu was looking at it). However, I don't see any results in Google as to this being a problem in Lucid.

I know ipv6 can cause a problem in this regard but having issued the command:
lsmod | grep inet6
I know that ipv6 is indeed disabled on my Lucid server. Any further information on whether the error reported in Karmic still applies in Lucid, and can this be addressed in any way?

Ubuntu Servers :: Get A Samba Server Up And Running To Share With Windows Machines?

Oct 14, 2010

i manged to get a samba server up and running to share with my windows machines. But i still want more. My main goal is to be able to share my movies. I have a laptop hooked to my flat screen with 3TB's of external drives, thats whats acting as my server. I have ubuntu desktop installed because i use it to play movies also.

I'm looking to set up something that is a little faster than samba (yes i no trying to share through USB 2.0 external drives and a wifi connection isn't going to be real fast no matter what) but i want to be able to access my server remotely. like maybe FTP? but what i'm asking here is what protocol should i use and what programs? i was thinking gadmin-proftpd and then filezilla to access?

Ubuntu :: Embeded - Nas From Usb Stick Slow Transfers

Nov 21, 2010

With Ubuntu 10.10 server installed on an
- AMD Athlon II X2 235E CPU AM3
- 2GB DDR3

Installed on a software raid 1 of 16 GB usb sticks that can sustain 24MB/s read and 13MB/s write rates
running
- ssh
- zfs-fuse installed from apt
- samba

With the zfs using the sata II controller, with a 2TB, 1.5TB and 500GB in a raidz1 (I know, it's uneven, I'll be changing them all to 2TB once I get the data off those drives).

However I'm experiencing a REALLY REALLY exceptionally slow zfs performance of only 600KB/s transfer rate even when using the command:

To test. CPU usage is only at 25% (with dedup=on) however I notice that the usb sticks are regularly transferring data during this write to the zfs pool. Also when doing a zpool scrub it completes 9.6GB of scrubbing in well under 2 minutes. Admittedly it shouldn't actually be doing much as no data was changed by me while the 3rd drive was unavailable.

I'm thinking that there is some data being temporarily saved to the main system drive (usb sticks) and then transferred to the pool, and this is causing a bottle neck. Note both 16gb usb sticks are plugged in to the same usb 2 host controller, but the combined write bandwidth of those sticks is not enough to saturate a usb2 bus.

How to track down this bottle neck?

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

Ubuntu Servers :: SAMBA Is Slow On Newer Machine?

Feb 26, 2011

It takes 45min to transfer 10MB from my laptop to my replacement server. It takes 1minute to transfer the same 10MB from my laptop to the old server.

All connections are equal. Both servers are plugged to the same router.

Details: I have decided to migrate away from my Proliant 1600 to a slightly newer less complex piece of hardware.

Both machines are LAMP installs. Both are setup to be maintained headless 99% of the time and gnome is launched from the command line only when it is needed.

The older machine has more things running on it than the replacement. The replacement has nothing running that the older machine does not have.

Old box runs Ubuntu 6.06 but was fully updated a month ago. Replacement box runs Ubuntu 10.10 and was fully updated just last night.

smb.conf was the same on both boxes other than the share locations. Reading trying to fix it myself, I did put some known speedup lines into the new box's smb.conf, but it did not make a noticeable difference.

Hardware:
Old box,
Proliant 1600 = 1998 small server tech. (weighs 50lbs w/o drives)
single 500mhz xeon (upgradable to 2 600mhz, though they are hard to find reasonably priced)
1GB SDRAM with ECC

[Code].....

It does not matter what share/drive/partition I transfer to on either machine. The result is always the same.

On the newer computer CPU usage rarely goes over 50% and it has not had to go into swap at all yet.

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.

Ubuntu :: 10.04 Extremely Slow While Booting Up?

Ubuntu :: 10.04 - Live CD Extremely Slow?

Jun 12, 2010

Have a little problem/annoyance. I was trying to use a Live CD with Lucid Lynx 10.04 x86 edition and the speed was incredibly slow. I took more than 10 minutes just to start. I noticed the CD drive stopped spinning (or spinning so slow I couldn't hear it) at times, then starting up again. I also noticed multiple i/o error in the logs after it finally booted up. The reason why I think this is a bug and not my drive/cd is simple:

a) The MD5ed the iso and even made two CDs with different burners. I tried older Ubuntu as well as several other Linux distros and the Live CD boot time is much faster (1-2 min). Tried the CD on a way, way older ancient laptop and i booted just fine and much faster.(I will provide any other info if needed).

Ubuntu :: Compiles Are Extremely Slow

At work, we use Ubuntu to compile large numbers of C, C++, Java, and AIDL files.My system is a Core i7 Quad-Core with 8GiB of RAM. Prior to this install, it ran Ubuntu 9.10, 32-bit. A basic compile took roughly 45 minutes.I just did a clean install with (x)Ubuntu 10.04 64-bit. After setting up the build environment to allow 32-bit libraries (mobile development), a compile took roughly an hour:15.

Ubuntu :: Extremely Slow Start Up?

Oct 10, 2010

I have had an extremely slow startup (upwards of a few minutes) for awhile now, and nothing seems to work to fix it. Regular boot time is far slower than it should be, and the time of logging in to a workable desktop is just really bad. I will log in, and then I will either get a blank desktop screen for awhile or an all black screen until the desktop will fully load with errors from gnome-panel and AWN not starting up automatically.Some of the fixes I have tried:

Disabling floppy from bios

Downgrading gnome keyring

Removing gnome* and gconf* from the home directory

Putting this script in /etc/init.d
#!/bin/sh
echo "nameserver 0.0.0.0" > /etc/resolv.conf

Here's my bootchart and a link in case the upload has problems http:[url].....

Ubuntu Networking :: File Server On 10.04 Machine - Slow Samba

May 22, 2010

I'm trying to set up a fileserver on my 10.04 machine, and access the files from Windows 7 via wifi. I can see everything alright, but the transfer speed to Windows never gets higher than 70KBps. Both computers can access the web at 800+KBps. I've also checked with an OS X machine on the same network, which was also extremely slow, so I'm fairly sure that the problem is on the server's side.

Ubuntu :: Extremely Slow Bootup In Karmic?

Feb 26, 2010

I know this has technically been posted but I think my situation is a bit different. People have been complaining that karmic is slower to boot. But from what I gather, it's only a few seconds extra due to an extra splash screen. I'm running Ubuntu Studio and mine takes like 5 minutes and is showing me 3 splash screens! 2 for regular Ubuntu and 1 for studio, which is the most sluggish of the three.

My computer is a Toshiba Satellite A75
2.8 ghz pentium M
1.5 gb ram
Radeon graphics
60gb hdd

EDIT: Also, recovering from hibernate takes a few min. Related?
