Under load, squid will always use 100% of the CPU. This is because it uses poll/select.
Ouch. That sucks.
(But, httpd uses poll - so why does that force 100% CPU usage?)
RHEL 3 sucks. Fedora Core 2 would have been a much better choice. Also, did you use poll? I know a large website that does several dozen hits per day using squid :)
Heh. RHEL3 is the Linux distribution we use within the ASF. (My local box is a mirror of the ASF Linux and FreeBSD setups.) Fedora Core 2 isn't an option.
Is it worth compiling my own squid then? (Read that as 'reboot my box to FreeBSD and use the squid port.')
On an OS that supports sendfile, a disk based cache will almost always bury a memory based one.
Agreed.
I don't think it's worth putting a lot of effort into mod_mem_cache. Doing zero-copy is just going to scale better than memory caching. -- justin
