We're running 3MB cache with the VM version, and Squid routinely consumes
around 60MB of memory including around 20MB of hot object cache in the VM
version. 32MB won't cut it. Squid has to keep a memory index of all
cache objects, and needs a certain number of bytes per object. The larger
your cache, the higher the baseline memory consumption.

Memory's cheap as dirt these days, go for a full 256MB or more. An 128MB
EDO DIMM around here is only $405, probably cheaper out in San Diego.

The CPU is not a limiting factor, I have a P-133 and handle around 110,000
requests per day, and Squid rarely exceeds 2-3% cpu.
