Your server is swapping extrememely (it must be). I've seen a similar effect
with my caches. I'm running 8Gb cache and it consumes up to 100MB (If I keep
the "memory pools" in squid.conf. Removing it improve things.)

I would suggest go for NOVM and remove the "memory-pools" from squid but
more RAM will help (go for 128 or better 256Mb)
