RE: Wrong number of cpus detected/reported

What kernels balance the loads properly? When I did some simple tests
with a dual Xeon 2.4, I couldn't get it Linux to balance properly.
About 30% of the time it would be off balance with two CPU bound
processes, and that is about the statistical rate. I think that was
with 2.4.20, but might have been 2.4.18. With 3 processes, one would
always get an unfair advantage compared to the other two.
