Exclamation Horribly slow transfer speeds with SAMBA


I've got a small network setup, with a SAMBA fileserver running Mandrake 9.1, and several macs running OS X. I'm trying to copy several gigs over to the fileserver, but I'm having horribly slow transfer speeds, of around 20 kb/s.

I have another linux box SAMBA setup on the same router, and it gets very fast speeds.

What can I do??

me too!

I've experienced the same from my Mandrake box to XP pro. Even slower than 20k! Anyone have any thoughts?

Exactly the same here. However, in my case the problem started AFTER I had upgraded from MDK9.0 to MDK9.1 using a powerpak with purchased supported.

After exhausting just about all avenues, I took up the MDK paid support- they replied "Not covered by what you (I) paid for") :-(

I've given up now and moved the large HD and file sharing back to the XP machine, until such time I stumble across a solution.

BTW, I there is no performance hit reading from the Linxu/ SAMBA box, only writing to it. Is that your experience?

Thanks

same here !

I also have the same problem with mandrake 9.2 rc2 (a fresh install)

Confused_bof : i also only experience this pb when writing to the Linux Samba server, not when reading from it !

Seems like we have something here... I have been searching for a solution for months now, tried everything i could : switch cables, NICs, hubs, autonegotiation... But i don't have enough Linux knowledge to further investigate...

Is there a guru round here ?

It's the first time i request help from a linux forum, i know how boring it is to repeat the same things again and again so be assured i've read that f***in' manual hundred of times, always found an answer by myself but this time... i'm stuck...


PS : sorry for my approximative English... I'm from the land of Frogs

I recently took a Linux server (RedHat 9 with stock SAMBA 2.2.7) and a PC running Windows XP and tried to track down a speed problem. It was my contention to start with that some patch or hotfix from Microsoft was destroying the performance. I started with a stock XP install without SP1 or any other patches and timed some accesses to the server. I then installed a patch, rebooted, tried again. I intended to go through each and every patch to find the culprit. After only a half dozen or so lunchtime rolled around and I left. When I came back the PC was agonizingly slow.. What the? This was one PC out of a batch of a dozen or so we were scheduled to install at a clients in a few days. Not knowing about the test I was performing one of the other guys installed Norton Antivirus 2004. Launching a custom Visual Basic app from the server that we write/support took barely <1 second before and upwards of 5 seconds afterwards. Incredible difference. I knew most antivirus software slowed things down _some_ but I was not prepared for this drastic of a difference. Incredible... We de-installed Norton and for kicks installed the one from www.free-av.com and the speed difference was barely noticable. Perhaps a second to launch that app now, not much more than that.

Anyway, some of the things I did prior to starting this Windows patch install fest:

1) Remove QOS Packet Scheduler. Not so sure now upon reflection if this is necessary or not, someone test with and without while copying to/from a SAMBA server and report back on the speed please. My thoughts are that it affected access to a SAMBA server much worse than to another Windows PC. Figures...

2) Stop the webclient. "webclient" is a service whereby all remote directory/file accesses are attempted as a web request "just in case" this might be a web-shared Microsoft resource or some such(?). It hits the server on TCP ports that SAMBA doesn't pay attention to and has to time out, causing a slowdown. Port 445 TCP comes to mind and in testing SAMBA 3.0 I noticed it did respond to requests to this port. I think the "webclient" hits port 80 as a sort of web request though. Stop it in services graphically or from a DOS shell via "sc stop webclient"

Good luck!

Thanx for that. Every little bit helps. Unfortunately neither helped in my case, although disabling my virus protection made a very minor difference.

But my money is on XP being to blame for the hit (see my post my post here

Thanks

I too suspect Windows being the cause of the problem. I use Windows 2000 Pro. Shall we continue this discussion on the other topic you made or here ?

Oh by the way, QoS is disabled here, and I don't see what you mean by "webclient". The dos command sc doesn't seem to exist on my French Win2K version...

Also, I have no antivirus software installed (and seems like i never needed one, never saw a virus in my LAN)
