Hello,

This time we can see I followed the original config. A page like
cnn.com takes about 60 seconds to load. Without the proxy it takes 10
seconds.

That sort of matches the relative number of parallel connections modern browsers will open to proxies vs to web servers.

You need to read this:

Note that if you’re behind a proxy (at work, etc.) your download characteristics change. If web clients behind a proxy issued too many simultaneous requests an intelligent web server might interpret that as a DoS attack and block that IP address. Browser developers are aware of this issue and throttle back the number of open connections.

In Firefox the network.http.max-persistent-connections-per-proxy setting has a default value of 4. If you try the Max Connections test page while behind a proxy it loads painfully slowly opening no more than 4 connections at a time to download 180 images. IE8 drops back to 2 connections per server when it’s behind a proxy, so loading the Max Connections test page shows an upperbound of 60 open connections. Keep this in mind if you’re comparing notes with others – if you’re at home and they’re at work you might be seeing different behavior because of a proxy in the middle.
