well, may be. may be not. since the load is high during buildworld i 
wonder if this has something to do with interrupt latency.

thanks

hmm...

can you please try BSD? just to see if it makes any difference. also try 
to disable PREEMPTION (with both ULE and BSD).

good

hmm... 1.5ghz, i wonder why your cpu is close to 100% during buildworld. 
it would be nice to know how much time system spends in "sys" etc. you 
have pretty fast cpu, so its kinda strange.

ah, i see.
