Lots of free memory on a buzy UNIX system is a waste. And no, your Squid did not ask for much.

They are all "free" kind of memory. To keep your sanity it's always best to look at the third line in free output (the line starting with "-/+ buffers/cache"). This shows the adjusted values which makes more sense to look at. In a busy system the equation is simply cached + buffers = total - actively_needed_application_memory - 5MB free as keeping more totally free is a waste.. (for simplicity kernel is included in "application_memory"...) What worries me is that you say the active application memory was only at most 70 MB before you started Squid, and your stats showed Squid using another 70MB, but the free output indicates 409 MB is now in use.. so something besides Squid is using a lot of memory in your system.
