I have been coding on a community for a while and now it is finished. Is there a way to find out how much memory it takes to run it and also calculate what equipment I need to run it?

What I need to know is how much CPU and RAM my script uses and some way to calculate how fast server I need to be able to host it.

Use the search feature and look at the CPU load.

I guess, it all depends of the traffic of your site. Even if your script is horribly slow, if you have 100 unique a day. It shouldnt be bad.

Search feature?

I have tried Zend to find heavy processes, anyone else used this?

you can also see how efficenet your program will run by just looking at the code..
