Really? I would have thought the linux kernel's disk caching would be far
less optimised for this than using a large squid cache_mem (whatever about
a ramdisk).

It's starting to look that way alright.

The cost of 8GB of ram was about €100, so it was relatively cheap. As you
guessed, the machine itself is 1U and doesn't have space for any more hard
drives.
