Re: Optimization/Benchmarking tools?

It's mostly trial and error here, and for that you'll want to use any of the web server benchmarking tools to help out ( such as 'ab' if you are using apache ). You might want to google up some of Rasmus's presentations on optimization to get a better idea on what to do. Here's a good one to get started on http://talks.php.net/show/tortech04/26.
