VIA & context switches

I have performance problems with a CUV4X-DLS (VIA-694XDP) dual processor motherboard. It's a web server. vmstat shows it does 10000-15000 context switches/s and load average stays aroung 20 all the time. I tried two other machines (a VAlinux UP and supermicro MP) with the same load, memory, SCSI controller, etc. (but different eth) and they run with a load average of 0.5-1 and 1000-2000 cs/s.

Bye.
