Unfortunately, you gave squid 4x the cache disk size, and the effect
is clear in the hit ratio, grately affecting the kB/sec. It makes the
comparison very difficult, as most of the stats are a reflection of
speed for hits vs. misses... Perhaps if you only told squid to use
1GB... Even then you have differences in drive speeds...
