The main bottleneck for a properly set up Squid cache is seek time. There
is generally to ways to optimize seek time

a) Buy a faster harddrive.

b) Use more than one harddrive.

For Squid two harddrives with 12ms seek time is a lot better than one
harddrive with 8ms seek time.

But all this assumes the system and your Squid is properly set up with an
async cache_dir type and the appropriate OS level tuning to allow Squid to
really make use of the hardware.

The choice of filesystems can only do so much and is not a substitute for
good hardware performance. A poor choice of filesystem can however make
the situation considerably worse.
