Ref:About the 5.10 'threads' scheduler
The 1st question in that post was answered; but I failed to dig down to the real kernel of knowledge I was looking for.

I am looking for data on the 'threads' paradigm in 5.10:

• User-land or kernel threads?

Answer: A Win32 Perspective:

• Kernel.

But what about Fedora 9 / Perl 5.10(pthreads) / Intel Core2 Quad processor?

? Does each thread receive an individual process time slice, or are all threads sharing a single process time slice?

? Can threads from the same process be distributed simultaneously onto different processor cores?

? How does thread creation overhead compare with vfork/execl overhead?

I am obviously going through some design quandaries picking an architecture. I am looking for relative capability data in this area.
