I just set up squid for the first time. I have zero experience with proxy servers. I used this guide:
(I also looked at a few other guides such as this one: http://ubuntuforums.org/showthread.php?t=320733. However, I wanted to most barebones config to start with and the link I used was the simplest.)
So now that I have it set up, I'm testing it with FoxyProxy. It is not working well. I went to speedtest.net. The download and ping tests were just as fast as without the proxy, but the upload test fails completely. Furthermore, many web pages load very slowly or not at all. So performance is very mixed, but mostly poor.
What should I look at first to begin to understand my problem? Thanks.
