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.
