Did it help? I compiled the same kernel with the 4BSD scheduler today and it seems that the processes jump accross cores too. My "eye" measure with "top" fells like it's more stable and probably converges faster to a stable state after "top" jumps accross cores. But in order to talk with numbers, I need to replace "top" with somethings that dumps the process number and the cpu id continuously in order to get some statistics out of it, otherwise you can just forget all the things that I have written. Is there an easy way to do that and are you interested? Regards, Momchil
