I am running a squid 2.7 on windows, and whenever I use it as proxy, it works really slowly, I should note I use a dynamic dns from NO-IP.
I've tried diagnosing the problem as they've said on the squid website, but came up with nothing.
Edit: Using Windows 7.
When I surf without the proxy, it works fast - it takes ~1500ms to load google.
When I surf in the machine running the proxy, it works fast - it takes ~1500ms to load google.
When I surf using the proxy, to load google, takes an order of magnitude longer, somewhere in the lines of 10 seconds.
