(note that forking is quite cheap operation on linux, don't know other OSes) This is quite different than what you are saying. > Each apache process (+ mod-php) is from 20Mb to 100Mb >regardless of whether it's about to parse a PHP script or not.

I'm not telling that your claims about speed are wrong, just that your claims about how mod_php works apparently are... -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
