Impressive. So the FPC implementation on top of this obviously does
something on top of this which causes it to slow down.
Possible culprits would then be the semaphores and TLS allocation.
I obtained the source to pThreads system late last night. It does use
a barrier using which is not necessary. And FPC (trunk) has another
barrier on top of that. I may re-compile pthreads library and update
on my machine but I think I already have it running up to speed!
Debugger slows things down too.
Present version of ThreadMemTest running outside debugger:
10500 threads create in 1.5 seconds :-)
What are the exact differences from this test to your last one? Would be
nice to know that... :)
