RE: [squid-users] How to increase the performance of Squid in acc elerator mode?!

I was also under the impression that storeio method "aufs" was the best
choice for Linux.

Another good thing to do (not Squid related) is use a PHP profiler to see
where your PHP could use optimization. PHP|Architect had a good article on
this: http://www.phparch.com/issue.php?mid=24 (no affiliation, I just
happened to read this edition). You might also look into using a PHP
caching add-on such as APC (http://apc.communityconnect.com/about.html).

The simplest action is to

  a) Make Squid conservative with the number of filedescriptors it uses by
disabling persistent connections and support for half closed connections.

  b) If your Squid is I/O bound then add more drives. Should not be the
case in an accelerator.

Then there is the more long term action of helping with getting Squid-3
and it's epoll implementation stable. epoll should allow Squid to manage
significantly more concurrent connections without wasting too much CPU.

And are you sure you want these?
