Some tips in reducing loading speed could be :

• Try to use more CSS

• Use GIF instead of JPEG . Try to use image files that take low disk space.

Answer 3

Google Chrome has some very detailed metrics for the request/response, downloading of the content, parsing, presentation, etc.

Right Click on a page and "Inspect Element". They also have a huge number of development tools tucked away behind that menu item.

Answer 4

If by "which elements" you mean which HTTP requested objects, then client-side tools like Firebug's "net" tab (see here) will help for simple cases and many less than simple ones.

If you are needing to diagnose elements within a scripted page then that will depend greatly on what language/framework/servers you are using.

And the free tests at:

Here's examples of the response time test and multibrowser tests:

I also use the built in features in chrome, but since I'm on a netbook in a country far far away from my server, there's too much going on to do reliable tests.
