Subject: e1000 poor network performance - 2.6.17-rc5-g705af309

Hi,

I recently started running linux on a new x60 thinkpad and started
noticing really poor network performance with this kernel. I saw some
archived threads from a while back saying this could be related to
conntracking. Disabled that (rmmod ip_conntrack) did not fix the
problem. I also tried disabling tso but that didn't have any effect
either. I can reproduce the problem when connected to a 100Mbps switch
(I don't have a GigE network to test this with).

This laptop uses the Intel 82573L (PCI-Express) chip. I'd be glad to
assist with any toubleshooting/testing w.r.t this. I am not subscribed
to the list, so please cc me on any replies.

Thank you,

Aravind.

First, lets move this over to netdev (see CC)

What kind of poor performance? what test? please send the output of
ethtool -e ethX and ethtool -S ethX after you've been having problems.

please provide more details and we can see if we can help.
