My pings to sites are relatively quick: ~6-7ms to Google.
However, when I load the actual site http://www.google.com Firefox measures it as taking 1-2 seconds on average. In fact, most websites appear to take that long. I've tested this with an out-of-network computer and obviously it's much faster.
Where do I start on debugging? Is there an easy way to do a kind of a traceroute, except for on the webpages?
