[svlug] Thread Programming part 2

A few people mentioned that fork is not that expensive... now.  In the
"good old day" (tm) :-), it was.  With newer UNICES, fork is no longer
as resource intensive as it used to be.  Linux is probably at the top or
near the top in fork performance.

A few years ago, there was a "friendly" :-) competition on comp.benchmarks
between Linux, *BSD to see who has fastest fork numbers based on the
lm benchmark from Larry McVoy.  It was interesting to see Solaris
down at the bottom.  Sun has done a lot of work since then and the
numbers gotten better.  At the time, some Sun engineers decided to
push threading because Solaris was ahead of Linux/BSD in that area.
Solaris now has fairly solid and stable kernel support for threads.
That is an area where it wins over other UNICES.

Linux still need work when it comes to thread...  which is another reason
why (IMHO) I think it is better to not use it on Linux, unless you just
want to learn how to program using threads.

Todd, by the way, if it seems like I was singling you out. Sorry it's
not intended.  Do post more details of what you are trying to do, that
way others can better help you.
