I just recently compiled the 2.6.12.3 kernel for my x86_64 machine
(Asus A8V motherboard); was previously running a SuSE-compiled 2.6.8
kernel (SuSE 9.2 distro). I'm now seeing extremely slow throughput on
the onboard Yukon (Marvell) ethernet interface, but only in certain
conditions. Going back to the 2.6.8 kernel shows no slowdown.
There a couple of possibilities, one is driver differences. SUSE ships
the SysKonnect vendor driver vs the older version in 2.6.12, and the
TCP congestion and TSO code has changed since 2.6.8.
Thanks for that tip. The SuSE 2.6.8 kernel had driver version 7.04, the
2.6.12.3 kernel had driver version 6.23. I just downloaded the current
driver from www.syskonnect.de (8.23) and installed it and now things are
much improved, getting around 6.8MB/sec throughput.
