sk98lin extremely slow transfer rate ASUS P5P800(2.6.17.7)

sk98lin extremely slow transfer rate ASUS P5P800(2.6.17.7)

[Sean Bruno]

I am experiencing a very slow(32Kbytes per second) transfer rate on an
ASUS P5P800 mobo.  This occurs on a special case where I am sending
individual 32Kbyte messages from a second server.  

I suspect the hardware, but am not sure how to come up with a 'good'
regression test for this issue.  

Configurations I have tried:

1. If I swap out the ethernet adapter(tried a intel 10/100 and intel
10/100/1000) the transfer rate jumps up into the MBytes / second.

2. If I do 'other' network activity on the box, like scp'ing' files
around, the transfer rate for my 32Kbyte packets goes up into the
Mbytes / second.  So I am a little baffled with the behavior.  

3. If I just 'scp' files around of various sizes the transfer rate goes
up into the Mbytes / second.



some of the relevant dmesg information:

Which driver skge or sk98lin are you using?  Sk98lin driver is being
obsoleted.

Yes, we will fix skge, sk98lin probably will stay busted...

You might be seeing checksum errors or flow control issues.

Look at ethtool stats (ethtool -S eth0) 
and try with hardware checksumming off (ethtool -K rx off tx off)

Thanks for the guidance.  Simply using the skge driver instead has
resolved the issue I was seeing.

Hi Sean,

Did you test with the current driver version 8.34, which is vailable on
our website?

I've already observed the same behaviour (8.31 though). The problem was that
after sending a few thousands UDP packets, then next UDP packets would not
go out without some TCP traffic to "push" them outside. This is a real problem
on NFS (where I first noticed it). But for me, it happened only on Yukon
cards and not on Yukon2.

Hoping this helps,

Hi Willy,

OK, I will try ASAP (not before end of next week though, cause I don't have
