squid

As mentioned in a previous post, I am having performance issues with a site I manage, One person has (forcibly) suggested using Squid as a reverse-proxy to improve performance. I have not heard that discussed in any Drupal meeting. I hear Varnish.

I have researched the web on both proxies and have found a lot of useful information, but (at least so far) not answers to these questions.

• Does anyone have experience with both?
• Are there any specific recommendations or concerns with using either?

Thanks,

Leonard Daly

We have a setup with a load balancer that points to 2 squid servers listening and serving as cache to 4 machines, and we have it in pairs:

squid1
|-www1
|-www2

squid2
|-www3
|-www4

Each squid is configure to send requests to their requests:

Quick question -- I run a (smallish) community site on a single dedicated server that is roughly 80% anonymous traffic. I've already installed memcache and apc on my server and tuned mysql etc. so things are running pretty good. In investigating how to make my site run as fast as possible, I've run across mention of squid.
