Excuse me for butting in here but this shows that fork AND exec is
slower than thread creation. I was under the impression that (for 2.2
or 2.4 at least) both fork and thread creation used clone (kernel not
libc). Only when a process does an exec does the diiference show
(well, actually it seems when either process modifies its stack).
Now, saying that, I have no idea how postgresql works so will shut up.
Sincerely,
