Debian: network performance

[SPF]

Today I started testing the network performance of the fit-pc2.

Unfortunately with ftp the speed was limited to about 3000 KB/s.

Currently running Lenny (Debian 5.0.4). So I thought about extracting the kernel from the images in this post:
viewtopic.php?f=46&t=1194

But that didn't work. So I went for adding the apt lines in sources.list:

Code: Select all

deb http://fit-pc2.com/download/ubuntu/dists/jaunty binary/
deb-src http://fit-pc2.com/download/ubuntu/dists/jaunty source/

And try to apt-get install linux-image-2.6.28-34-fitpc2.

But this had one dependacy: wireless-crda. Which is not part of Debian.

So I also added some Ubuntu apt lines:

Code: Select all

deb http://archive.ubuntu.com/ubuntu/ jaunty main restricted
deb-src http://archive.ubuntu.com/ubuntu/ jaunty main restricted

## Major bug fix updates produced after the final release of the
## distribution.
deb http://archive.ubuntu.com/ubuntu/ jaunty-updates main restricted
deb-src http://archive.ubuntu.com/ubuntu/ jaunty-updates main restricted

Did an apt-get update and apt-get install linux-image-2.6.28-34-fitpc2.

After reboot the speed I got with ftp was 20476.75 KB/s.

Don't forget to comment the lines in sources.list after installing the new kernel.

Is 20000 KB/s fine with you guys or should I get much more out of the fit-pc2?

20MByte/s is in the same area I see. This value is 2-3 times below my expectations. Unfortunately there seem to be not so many gigabit ethernet users our users that care about network performance. I tried to compile the Realtek driver as a module, but the vendor driver is not working with my VLAN setup. At the moment I use a vanilla kernel 2.6.32.x.

I have no idea if this is a problem with the Intel chipset, a Realtek problem or a driver problem.
