Re: How to get cpu consumption of a php script

Please take into account that lighttpd does have some random high cpu-consumption problems, it could be that also. Give nginx a try instead. Also: microtime by itself isn't enough, sum time() to it because if a script lasts more than 1 second you can end up with negative total time, microtime doesn't have a seconds counter, only microseconds. Are you using a cms? Have you tried deactivating some plugins?
