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.

I've just managed to access my windows share from Ubuntu but am now getting write speeds (to xp share) of only 9MB/s over my wired network, anyone have any ideas as to why this may be? I've googled but can find no specific answer.
My NIC is:
Ethernet controller: Broadcom Corporation NetLink BCM5784M Gigabit Ethernet PCIe (rev 10)
(from lspci) on a Dell studio 1737)

I have a 500gB USB drive connected to my laptop for backups and filestorage. But I can't get it to play nice with Midnight Commander. My transfer speeds max ut at 2MB/s wich is painfully slow when moving large files such as movies. Worker FM transfers the same files to the same drive much MUCH faster (not sure by how much, though). This leads me to the conclusion that the problem lies with MC.

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.

About NFS.
Server:
Client(s):
Code:
I have followed Robbie Workmans' HowTo [url]
Reading and writing works absolutely fine with small files but large files are tediously slow in writing to the server. (rw,no_subtree_check) are options in exported directories.
What is your experience with NFS and how can I speed up large file/folder transfer(write) speeds?

I tried using my USB to transfer a 500MB file, the speed came up as 1-130 kb/s. That is pathetic. I should be getting more 25MB/s.

I am struggling trying to understand the reason for a fairly slow data transfer rate between two machines. ( tried point to point and also via a 1 gb switch )
One is nfs/http/ftp server ( with raid1 and lvm on top ), the other one my desktop pc. Both OS with default options, no changes to kernel in proc or other sort of thing.
Hardware is full recognized and perfectly working: The server has 4gb ram, Intel Core 2 Duo CPUE6850 @ 3.00GHz, 1000Mb/s NIC card and Lucid 10.04 64 bit, 250Giga Hard disk. The client has 3gb ram, Intel Core 2 CPU 6320 @ 1.86GHz, 1000Mb/s NIC card and Ubuntu Maverick 32bit , 150Gb Hard disk.
Raw data is good:
gettons@gettons-desktop:~$ iperf -c MYSERVER

I have read many threads but cannot find a solution on this code...
Now no matter how i transfer if its from HDD to HDD or to SSD i never get more then 18-20MB/sec, i just tried booting to my live CD and was able to transfer with 24-25MB/sec
This is really slow, since the worst (2.0TB) can do a minimum of 30 READ
Anybody got any ideas, this seems to be something that has plagued ubuntu for years, and no i don't want to try other distros, i tried almost all of them a year ago and finally went with ubuntu

I'm at the end of my rope here. And the most frustrating part is, I've found many posts all over the web from others who have had similar problems, but they ALL seem to be older distros and those solutions don't work for me. "Find Similar Threads" only yields one thread, and I don't have the file mentioned in the answer (the original poster didn't either).
Computer: AMD 64 Quad core, USB 2.0 on front bus, dual booting Vista and Ubuntu 10.10
Device: New Sansa Clip+ 8GB mp3 player
Problem: When I transfer files to my mp3 player in Ubuntu, I max out at about 150 KiBbps. It's painfully slow - it takes me half an hour to transfer 300 MB worth of albums. I had similar problems with an older player that may have been usb 1.1, but this one is brand new. And when I switched to Vista (first time in months, thankfully), I was able to transfer the same files at upwards of 3 MBps. I know that flash devices often can't write anywhere near the max speed of USB 2.0, but obviously it can do a whole lot better then 150 KiBps!So, same hardware, same files, different OS - the problem must be with my Ubuntu config.

I got a new machine with GA-p55A-ud3 mobo and a WDC WD10EARS 1T disk. When I tried to benchmark the disk IO, I was suprised by the low write speed:
[Children see throughput for 1 initial writers = 35962.63 KB/sec
Parent sees throughput for 1 initial writers = 35962.63 KB/sec
Min throughput per process = 35962.63 KB/sec

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

I'm trying to transfer some files to my USB stick, and it's transferring at the most pitiful rate, around 200-400kb/s, occasionally shooting up to 1MB/s, but not for more than a few seconds.
I realize a lot of factors can play into this, so I'll try to provide as much detail as I can.
I'm using OpenSUSE 11.3, KDE 4.6 RC2, and a Corsair Mini Voyager 16GB. My motherboard is a Gigabyte EP45-DS3L.
dmesg output:
Code:
lsusb -t output:
Code:
Sometimes too, the transfer just stops all together. It just... doesn't transfer for a while, then it'll go back to 400kb/s etc, then it'll stop again for a minute.

We have a server and we have instales an Open suse 10.3 on it. We created a Samba server also. Made to share folder, that we acces from network from other computers that have xp.
The problem is if we try to copy from server it is very slow only 100-300kb/s. The strange thing is that if i copy 1 file then its slow but if i start to copy another one the speed gos up to 10-15mb/s. Evry time i want to copy somethin or install from that server i need to start another copy. If i copy from a comp to that server the speed is normal only if i copy from server its slow.

I'm experiencing slow speed transfer between two wireless connected laptops running ubuntu 9.10. Using SSH to tranfer files between these two laptops, which connect to the internet via a wirelesss router, with good speed. This is why I'm surprised by this low speed : 52.3 KB/s, averaging 3 hours and 31 minutes for a 700 Mb movie. Is there any way to make this faster ?

So what kind of speed are you getting with Samba over your local network? What speeds should I be seeing? I'm currently transferring a large amount of files from one computer to another. I'm taking everything off of a desktop drive on computer A and putting it on an IDE disk on computer B. Transfers are running at around 600-700 KB/Sec. I've seen moments, mostly when the transfer starts, where speeds were at 1000KB/Sec, but that lasts a very short while and then starts to "degrade" until it reaches 600+ KB/Sec. It then seems to level off there. Is this acceptable? Is this all I can expect to get out of a 10/100 home network? The current transfer is 2.5GB. Looks like it will take 1 hour+ to complete. Transferred 12GB last night. Was looking at 4-5 hours to complete so I left it running while I was sleeping. Personally, I think this is slow. I think it could be exponentially faster.
While I'm running these transfers I'm looking at some documentation on Samba speed tweaks. I've been adding little tidbits here and there to both smb.conf files. Some of it seems to help. Sometimes there is a noticeable difference in speed. Sometimes the changes actually cause degradation in speed. If you have a speed tweak that you would like to share the information will be gratefully accepted. Samba gurus welcome to reply. How do you set up Samba in an office environment? How do you set Samba up in an environment where performance is critical?
Maybe I should forget about Samba and try using a different transfer protocol? Am I expecting too much from Samba?I should stop before I really start to ramble. Anyhow, networking beats the heck out of the sneakernet, at any speed!As a side note, or maybe quite importantly, there is a router and a network switch (not a hub) involved here. Maybe something to consider?

(this is a repost of the same thread in the networking/wireless forum, I think it's better suited here but couldn't see a way to move it) I have a Proliant Microserver, I have Ubuntu Server 10.10 installed onto to a USB stick (the server has an internal USB port). The storage drives are Samsung SpinPoint F1s. The server is plugged into a gbE switch, there is a link from that to a 200mbps powerline link, from there it goes to a 100mbps switch and then to my machine I was testing from.
I realise that a powerline link can often slow things up, but I use the same link for my Internet connection which will happily pull files down at around 4.3mb/s.. so I know the link isn't the bottleneck. If i copy anything via any of the samba shares then it transfers at around 1.5mb/s. This speed does not change if I try plugging the client into the same gbE switch as the server. Similar spees are shown if i transfer it over http via apache2 as well. Client machines are laptop running ubuntu and a win7 desktop. Speeds are the same copying to both of them. I have applied tweaks to samba as described here;

I currently have a Samba share on a Debian 7 system. This share was only ever used by Windows systems on the network.
I just finished setting up a Debian 8 system with Xfce, and now I would like to connect to the share. I already installed gvfs-backends and gvfs-bin. When I go to Thunar file manager, and click browse network, I'm presented with a "Windows Network" shortcut. When clicked it says: Failed to open "Windows Network". Failed to retrieve share list from server: No such file or directory.

Is it possible (on lenny, in case that matters) to backup some directories with rdiff-backup, with the target being a WinXP Pro Host, i.e. the target being a SMB share? My idea is to start the XP-Box over WOL, run rdiff-backup and then shut it down using "net rpc SHUTDOWN"...

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

My Sempron LE-1100 home server (1GB RAM) has run CentOS 5 32-bit happily for years, but I decided to replace its two Seagate 250GB drives (RAID1) with two WD 500GB black drives (RAID1). I decided to do a fresh install and used CentOS 5.5 64-bit this time. Since switching to the 64-bit OS with the new drives, my transfer speed across the LAN has dropped from a reliable 45MB/s to only 18MB/s from other machines to the server, and to 27MB/s from the server to other machines on the LAN. I use gFTP or WinSCP for these transfers (in FTP mode). Prior to installing the new WD drives, I ran the long WD tests on them and they passed, so I don't believe the drives are faulty. I suspect it's more to do with me switching CentOS from i386 to x86_64.
I've got two questions:
1. Is the 64-bit version of CentOS appropriate for a Sempron LE-1100 with 1GB ram, or should I switch back to the i386 version?
2. Is there a reason why switching to the 64-bit OS would negatively impact on transfer speeds? I doubt the new HDDs are faulty...I was expecting them to be faster.
3. Is there anything I can try to improve transfer speeds across the LAN?
According to PHPSysInfo, the network card is "Ethernet controller: nVidia Corporation MCP67 Ethernet".

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

From Window 7 client 1 TO Windows XP client 1
40-50 Mb/sec
From Window 7 client 2 TO Windows XP client 1
50-60 Mb/sec
Copying file from Windows 7 client 2 share -> TO Windows XP client 1 show me 100-120 Mb/sec speed permanent.
Copying file from Linux hosts to NFS server is stable 50-90
Mb/sec bidirectional.
This part of my smb.conf file

I've got a fresh Wheezy/Xfce install.I'm trying to access a remote samba share the gigolo way. It is an external USB hard drive connected to my router. I can access it read only using the following URL with Icedove: smb://bbox/
Anyway, this is just to try and give might-be-useful information, but ultimately, I don't really want to use fusesmb. I would rather have the gigolo way working, allowing local network shares browsing, auto-connect, etc.

I've tried over options, as well, but it isn't automatically mounting. Any suggestions (including where to file a bug report)?

I am having slight issue with setting up file sharing. I have a windows 7 pc and hp proliant microserver running. I have a raid array which I am using as a share for storing music, pictures etc. When I reboot the debian server I can't connect to the server from the windows 7 PC (I have mapped a network drive) until I go on to the server and restart samba with /etc/init.d/samba restart - then everything works fine. I can ping the server with both ip and hostname but the network drive does not connect - this is straight after a reboot. Is the /etc/init.d/samba restart doing something differently to when the server boots? I have read several posts relating to printer sharing issues which point to samba not starting before cups so I am wondering if samba is starting before some of the relevant networking services.

I've done this a million times, so sure it is something simple. I just set up a file server with three drives. One is small and faster that houses all the system files. Then the other two are slower but larger (WD Green: variable 5,400-7,200 RPM) drives in RAID0 then encrypted using Blowfish 256-bit. Hence the performance double then hit below in the buffered reads.
Code:
Debian-Server-023 ~ # hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 1650 MB in 2.00 seconds = 825.44 MB/sec
Timing buffered disk reads: 234 MB in 3.02 seconds = 77.41 MB/sec

I have a Hitachi SimpleNET adapter (entry-level NAS device) on a Seagate FreeAgent 1TB external HDD (formatted ext3). The NAS device is connected over 100MB/s ethernet to a Netgear Wireless G router. All other devices connect using Wireless G. The NAS runs embedded Linux on an ARM processor and it runs vsftpd and Samba for file transfers.
If I transfer a large file using an FTP client the transfer maxes out at around 2.5MB/s. For my purposes that's good enough, especially considering the Wireless G bottleneck. If I transfer a file from a Windows 7 client (using samba) I get around 2.2MB/s. I know the CIFS protocol has more overhead than FTP and the difference in speed isn't that noticeable.Any combination of Ubuntu and Samba results in me getting less than 1MB/s. I've tried mounting it through Nautilus (GVFS) and /etc/fstab. FTP from this same Ubuntu client gets around 2.5MB/s.
I don't have root access on the SimpleNET to change the smb.conf. I've made a few adjustments to the mount options with no success. how to either speed up 10.04 as a Samba client or mount a folder on an FTP server locally? I've tried both curlftpfs and FUSEFTP. With curlftpfs any write operation results in an I/O error and it crashes intermittently. With FUSEFTP I never got that far and couldn't even browse the folder.
