no matter how you tweak and optimize the same old architecture of a given OS,
still squid req/sec throughput will not significantly increase. squid bottleneck
is the disk i/o and you have to develop a new technique/algorithm to improve
disk i/o. adrian did the right thing to improve disk i/o performance, he is
working right now with his IFS. i believe this will significantly increase the
req/sec throughput of squid.

for more info about his latest work, click this url:

oh btw adrian, when is the tentative date to release your IFS? :->

fooler.
