Dan, you probably want Yahoo's YSlow or Google's Page Speed. If you think it's images, or a number of other front-end issues, a code profiler probably won't help you.

He spoke at Google I/O this year about website performance and his talk is available on YouTube: http://code.google.com/events/io/sessions/EvenFasterWebsites.html http://stevesouders.com/ (other videos and posts) On Sep 2, 2009, at 7:44 PM, thin wrote: > There's an excellent bit in the firebug [firefox] plugin that is good > for analyzing various element load times. it doesn't specifically do > php, but it'll tell you about various ajax call load times and > elements [eg: images] too. might be a good place for you to do some > sniffing. > > > > On Wed, Sep 2, 2009 at 8:19 PM, Daniel C.<[email protected]> wrote: >> A friend of mine has a site (written in PHP with lots and LOTS of >> Ajax) that's loading slowly.
