Forking in Linux uses COW (copy-on-write), so a freshly-forked process occupies maybe 3-400 bytes of RAM. Only when writing on a memory location, that location gets allocated. There are advantages (it is more safe, as you can't overwrite other processes' memory) and disadvantages (you can't simply read or write memory to communicate between threads, but must use IPC). But speed and memory consumptions are not an issue. Bye. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
