My experience with sites like Google or similar is, that in most cases 
(99%) the problem is not due to the fact of response time as these sites 
are optimized for high loads.
BUT Firebug! Because it takes time to parse and analyse the code.

So if I experience "slow" response times on a site I disable FB first to 
see what happens.

It might be a legal issue to cache external code without taking header 
information into account. I'm not an attorney...
