Squid uses epoll and kqueue on Linux and FreeBSD, and has been doing it for some time. Squid 2.7 also supports Solaris' /dev/poll (squid 3.X doesn't) nor MSWindows' Overlapped I/O and Completion Ports. I suspect that the Varnish documentation is a bit out of date. > But I know it is not true, I have been using Squid for years and think > squid is very efficient and fast enought to serve massive clients. So > I want to know if any hidden secrete behind? It's hard to have any secrets when the code is in the open :P Squid is reasonably efficient. It can be - and hopefully is being - still improved. > What is you guy comments on those issues ( c10k/epool etc) Some of the most obvious issues have been addressed. There's still lots to do tho. -- /kinkie
