Nicolas, I know that posix_spawn exists now in Solaris.
But I measured that it has no benefit over the traditional vfork and
exec sequence of calls, but the authors of posix_spawn designed it to
be an improvement if *implemented* in the kernel. The lack of
performance difference between posix_spawn and vfork,exec and the
*very* bad performance of vfork,exec on Solaris - compared to Linux on
the same hardware, where 2.6.25.20-0.5-default can spawn utilities al
most 70% faster than Opensolaris B134 - has lead to my request to find
some one to try and improve the situation.


What does DTrace tell you about where the time is being spent?
Instead of asserting where the problem is in email, how about
doing some investigation?
