Either you load the whole database into your PHP script;) or... there is a programming failure in your scripts (loops, etc), which I would consider to be the case here... It looks like the script is never ending and therefore it doenst free up memory... > My questions: > Is it correct to assume that the memory is the main bottleneck? > How much memory should I expect each connection to consume? > How much memory do I need to be able to handle 1000 simultaneous > connections? *g* Memory and disk I/O are always bottlenecks. The server capacity obviously depends on what you are serving. but I assume you'd be able to serve 1000 simultaneous connections on a P60 with 64MB RAM (serving static pages...) hope that helps, -p PS: btw: also check your Kernel - I know only from linux, but a standard kernel is probably not able to serve 1000 connections.
