It would be interesting to see a similar comparison using Squid 1.2 with
async-io disabled as well :) Both to see how much persistent connections help
(compared with Squid 1.1) and what is the gain from using async-io (compared
with Squid 1.2 with async-io enabled).
Of course, any good performance analysis requires running a lot of tests
under different conditions/scenarios. Even if vendors do that internally,
they are interested in posting one result showing their product wins the
most. Clearly, that one "lucky combination" is virtually guaranteed to be
very rare in practice..
