Fascinating!!! This is about the coolest thing I've tried in a while.
Never noticed the net tab before.
I just tried a few sites -- amazing results. My own site that I'm
developing varies from 300ms for a cached page (why are those cached css
and js files still taking so long) to more than 2 seconds when it has to
load all those stupid images that we never realize we've accumulated.

I cannot recommend the Firebug extension for FireFox enough. It has a
"Net" tab that will show you, in detail, how long each subrequest
takes. You think that the browser is caching js and css and all those
images. But unless you have agressive caching turned on, it still
makes an HTTP HEAD request to the server, and waits for the response,
to find out if the cached resource has changed.
