How to find processes that are slowing things down

Hello,

I do not know a lot about this but is there a way to run my site throught some sort of reporting tool that will tell me which functions take longer to run than others. I want to try to speed things up a bit and consolidate some of my code, not to mention find some 'best practices'.

Thanks for the help.

But remember that "The best is the enemy of the good" and most scripts are usually so small and fast that users won't notice any speed degradation.

All advice is supplied packaged by intellectual weight, and not by volume. Contents may settle slightly in transit.

firebug and chrome's dev tools both have profilers, though firebugs gives you a lot more stats than chrome...


chrome also has the task manager.
