Yes, I realize it's a bit old but I just wanted to make a small point that forking is slower. It's funny you should ask because thread creation on Linux has in fact improved over process creation much more in 2.4 kernel.
Benchmark at IBM shows Linux 2.4 thread creation is 30x faster than process creation. Process creation on Windows 2000 is about twice longer than process creation on Linux. This means forking on Win32 will be 2x slower! See 2002 benchmark below: http://www-106.ibm.com/developerworks/linux/library/l-rt7/?Open&t=grl,l=252,p=mgth Cheers, --- Andrew Dunstan <[EMAIL PROTECTED]> wrote: > sdv mailer said: > > Forking is expensive on many systems.
