It's the MaxRequestsPerChild > or something 'tunable'. There appears to be a terminology conflict here -- Apache uses one child per connection, which may serve multiple requests. Zeus uses one process to handle all connections and requests, as it just puts all the connections into a select() or poll() (dunno which) and does its own switching between connections instead of letting the OS do it. Zeus slaughters Apache in performance. Apache is more stable if you do strange things to it. It's easier to write modules for Apache, since if your module crashes you lose a child. In Zeus, if you were to introduce code that runs inside the server kernel, you'd crash the entire site if something went wrong. -- tani hosokawa river styx internet To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
