Hi there! I'm doing some experiments on caching HTTP requests in the middle of the way between my webservers to the SOLR load balancer (lvs). What I need to achieve is an extreme hot cache in the fastest possible way. The trick is that objects don't live longer than 15 minutes :-( This is because the "objects" (in Solr language, searches) are likely to change between that 15 min period. Unfortunately, that's a requirement, unless so far until I learn more how to write Squid plugins to play with timeouts and stuff like that, which hope it's soon :-) The interesting part is that the incoming traffic handled by my squid is averaged 20Mbytes with peaks of 45Mbytes/s, with a hit ratio of 25 to 30%! It's awesome to see how great it behaves! The reason why I send this message here, above from thank you about this amazing software, is to see if I could get some tips I miss to suck the most I could from Squid in the way to store/get objects as fast as possible. I've compiled Squid version 2.7.STABLE6 with this parameters: '--prefix=/usr/local/squid' '--bindir=/usr/local/bin' '--sbindir=/usr/local/sbin' '--sysconfdir=/etc/squid' '--localstatedir=/var' '--mandir=/usr/local/man' '--infodir=/usr/local/info' '--disable-internal-dns' '--enable-async-io' '--enable-storeio=diskd,aufs,ufs,coss' '--with-aio' '--with-large-files' '--enable-snmp' '--with-maxfd=8192' And I attach my conf below.
