Now, if by gzipping you mean that the file is being compressed _before_ caching, that is fine, else you are just wasting CPU cycles at your proxies. I would bet that apache would most probably _not_ gzip before caching, but squid will probably do. Just a guess. Yep, that is expected.

Additionally our old sysadmin who works at MySQL now recommended we try Lighttpd with mod_cache and mod_compression so we'll be doing some testing with both of those solutions. Ignacio, we've found that putting the gzip compression on the proxies balances out the CPU load better, otherwise the proxies just sit there with a 0.01 load avg doing IO.

Compression consumes some CPU, so the proxy seems not the right place. If contents are to be cached it would be no big deal. Can you do the gzipping in the web application, not at the proxy?

The commercial solutions like F5, Cisco, and Zeus have it and we have it working with Apache and Mod_proxy but we're finding that Mod_cache is buggy and occasionally crashes under heavy load.
