The r8169 nic performance regression is still there.
2.6.22: send 82MB/s, receive 86MB/s
2.6.23-rc9: send 32MB/s, receive 98MB/s
I debugged this with Francois Romieu but haven't heard from him since
testing his fixes.
I attached a patch from him which is a partial revert of commit
6dccd16b7c2703e8bbf8bca62b5cf248332afbe2.
With this patch I get 93MB send and 97MB receive and I have been running it
for a week but I don't know if the patch has any downsides on other
systems.
