Setting the FD limit to a ridiculous high value (like 131072) is a bit dangerous if you are using select or poll (the default connection polling schemes), because the kernel has to spend too many time checking each FD state on each squid main loop. If you are using epoll on Linux that danger dissapears, as CPU usage becomes rather independent on the number of open FDs. epoll is enabled by adding --enable-epoll in ./configure args. So, setting max_fd to a really high value and using epoll makes squid much more scalable. HTH, -- Gonzalo A. Arana
