Ha! Since I have put vanilla 2.6.27.9 on the server yesterday, but compiled it
with distro configuration, I decided to try a minimal "optimised" config for
this machine today.
With a reconfigured and recompiled kernel skge outbound performance went from
13 Mb/s to 17 Mb/s so it seems there was something in there which was really
hampering it.
Kernel configs are radically different so I am not sure if there is any point
in sending them here? And I am also not sure if I will be able to spend any
more time trying to pinpoint which config option was to blame. But if I will
I will of course report my findings.
