I am trying to configure squid for the optimum performance(fast). uname -a Linux gateway 2.6.27.19-5-default #1 SMP 2009-02-28 04:40:21 +0100 x86_64 x86_64 x86_64 GNU/Linux # /usr/local/squid/sbin/squid -v Squid Cache: Version 3.0.STABLE18-20090824 configure options: '--prefix=/usr/local/squid' '--with-dl' '--with-maxfd=32000' '--enable-snmp' '--enable-carp' '--enable-arp-acl' '--enable-htcp' '--enable-underscores' '--enable-stacktraces' '--enable-delay-pools' '--enable-useragent-log' '--enable-referer-log' '--enable-forward-log' '--enable-multicast-miss' '--enable-cache-digests' '--enable-auth-on-acceleration' '--enable-storeio=aufs,diskd,null,ufs' '--enable-linux-netfilter' '--enable-removal-policies=heap,lru' '--enable-icmp' '--enable-large-cache-files' '--enable-x-accelerator-vary' '--enable-follow-x-forwarded-for' '--with-aufs-threads=44' '--with-pthreads' I am looking for the comments and suggestions for the 'configure options' I used, but esp for the following options --with-maxfd=32000 --with-aufs-threads=44 --with-pthreads are they optimized and recommended ?
