Subject: idea to enhance get_pid()
Date: Sat, 20 Apr 2002 09:15:15 +0000 [thread overview]
Message-ID: <F74PKipeUekcMrvgldU00000fc8@hotmail.com> (raw)
Hi there,
I've got an idea to speed up linux/kernel/fork.c/get_pid(). Why not use
bitmap to alloc/free the pids? Is it because 4KB(32K/8) memory scanning is
slower than the current get_pid() version? Does anyone benchmark them?
Thanks,
Lenny
