I have a dual Athlon MP computer, and I have a very recent version of
FreeBSD 5.3 running on it.
If I start 6 computer intensive processes, and then kill 3 of them that
are using (say) processor 1, then the other 3 processes are all
processor 0, and as such only get 33% computer time each.
Under FreeBSD 4.10 they would have got 66% computer time each, because
there each process didn't seem stuck to a particular processor.
Is there a sysctl variable that controls this, or is this a bug in
FreeBSD 5.3, or what is going on?
Here is the computer intensive process:
main() {
int i;
while(1) {i++;}
}
