As Squid is an I/O intensive app, I have been working with a major user of
Squid running on Linux RH 2.2.16.(bespoke). Hardware no name 512MB, single
p2 300. Two test machines have been setup, One with a platypus Qikdrive
www.platypus.net (SSD 2GB capacity, upto 10MBps/15k Tps/Access times - 3/10
MICROSECONDS. The other with 2GB Scsi HDD.

After considerable testing there is no performance gain as far as HIT access
times are concerned. According to the drive spec/requestsPs equation one
would expect a significant improvement. (requests/sec1000000/access time).
Cpu and Bandwidth are within tolerances.

Does Squid use DISKD to cache to RAM? Are there any configs that need
changing? Any advice,comments would be greatly appreciated.
