Acceptable CPU Usage

[leon]

What is an acceptable CPU usage for an application in PHP 5? It takes up about 0.5% on my development machine (3 GHz). Is it too low or too high? Any recommendation? Thanks.

Half of a precent sounds pretty good to me. I'd say high is around 25%. You want it to stay as low as possible.

My CPU Usage for PHP is around 5% at any time so I'd say .5% is pretty good. I run a lot of websites and a ton of PHP scripts though.
