Another Slow Upload and Download Speed Thread
-
[quote=“Polii123, post: 44685, member: 28818”]I also put down compression, but that didn’t change anything.
Im on SVN 3178.[/quote]
Am I mistaken?
-
I meant we didn’t touch the compression before the problem occured.
Iperf result on the testing client, is the same as the one i posted.
-
I agree with Tom, that you should try to image /w the client on the same switch as the FOG server.
Speed may not be the issue, but something else might be. Eliminating variables in the problem is the name of the game.
-
The device you’re using, T540p, isn’t listed in the problematic devices or working devices, in the WiKi.
Are you experiencing the slow imaging speeds on every client? Or just clients of this model?
-
Every client. T540p also was on 5GB/min.
-
what network card is in that computer?
-
Intel Ethernet Connection I217-LM
-
Just thought of something…
Could you do a health-test on the FOG server’s image storage drive?
If it’s failing, that will explain what you’re seeing.
-
Maybe this can give us some more insight?
-
bump…
Any updates on this?
-
The quality of the switch can make a tremendous difference as well. Recently we replaced 10/100 Allied Tellison switches with 10/100/1000 HP ProCurve Switches in a laboratory environment. Incredible difference in reliability of transmitting and recieving, as well as bandwidth with multiple synchronous images

Hi,
There is a simple tools to check the bandwith of your network : [url]https://iperf.fr/[/url]
A java frontend here : [url]https://code.google.com/p/xjperf/[/url]You can test TCP/UDP bandwith.
I use it before deploy in multicast.

Sorry I was sick over Easter thats why i didn’t write here.
I contected the client directly to the core switch today, but that didn’t change anything.
-
Have you checked the server’s hdd health ? Checked the RAM health?
-
How can I do that?
-
I found this: [url]http://unix.stackexchange.com/questions/124790/how-to-check-health-of-hard-drives[/url]
But if it were me, I’d probably shutdown the FOG server, and boot up to the latest version of Hiren’s BootCD. Normally you have to find a torrent of it and download it that way. It comes with a SLUE of utilities.
If the hard drive is failing, that’d explain your speeds during imaging.
-
Ok, will try that on monday.

Hello Polii123,
Did you figure it out? I have the same problem. After upgraded from SVN 25xx to 3291, uploading/download speed become so slow. I used to get about 1GB upload and 1.4GB download but right now upload and download cap out at 700MB.
thanks

Doublecheck your compression settings. the hardware AND your network performance determine what’s the best setting for you.
At my building, with core i5 DDR3 systems and gig network throughout, I favor 6 or 7 for compression. -
Thanks Wayne. You nailed it.
It used to change to 9 by default if you don’t touch compression rate but on svn 3291 it says at 0 if you don’t change it. Should 0 be faster when uploading? maybe compress algorithm has been changed since svn 25xx. I get over 1GB on 1, 400MB on 9 and 700MB on 0 for uploading. Selecting 1 through 9, download speed is back to normal. I updated to svn 3330 which addressed this and some other issues. Thank you.
