I have been use squid iptables to get load balance and reverse proxy and it works for half a year. But now traffic goes up . and i use five squid box to load balance. when traffic high ,squid use 50% cpu , and it is slow to visit static pages but the total traffic is about 40M . and every squid box has about 1800 ESTABLISHED . i did some optimize such as , net.ipv4.tcp_max_syn_backlog = 4096 net.ipv4.ip_local_port_range = 16384 65534 use ulimit âHSn 8192 ââenableâasyncâio diskd configure squid-2.5.STABLE5 and use refer log patch
--prefix=/data/squid --enable-useragent-log --enable-referer-log --enable-default-err-language=Simplify_Chinese '--enable-err-languages=Simplify_Chinese English' --disable-internal-dns --enable-storeio=ufs,diskd,aufs --enable-cache-digests --disable-ident-lookups --enable-async-io=160 I wanna to know what is the squid high performance and how can i get it ? Thanks in advance
