Profiling tools for client side optimization

Question

I have to perform a client side optimization for our site (server side on Java). Yesterday I read some articles about it and create a plan how to do it:

1. Find tool for profiling the site to see the effect of optimization
2. Perform the optimization

Could you please suggest some tools for profiling web-sites and some useful articles about that? I found a lot of articles about optimization itself, but about profiling nothing useful.

edit: any automated solutions will be good :)

Answer 1

I found some info that helps start from scratch if you are new one in client side profiling/benchmarking.

Chrome DevTools presentation by Ilya Grigorik, very interesting and useful.

Speed tracer is another useful tool for benchmarking (as well Chrome Extension).

Answer 2

Just came across speedcurve.com not sure how well it works but it looks very promising.
