That means the total number of connetions (both client and server) plus disk files Squid can keep open at any given time is up to 65535. A cacheable cache miss of noticeable size uses 3 (client, server, disk) A cache hit uses 2 (client, disk) A memory cache hit uses 1 (client) A non-cachable requests uses 2 (client, server) Persistent connections stay used between requests, optimizing the setup time for the next request (eleminated), making a huge difference over WAN links. With 65K filedescriptors you can probably support somewhere in the range of 30k-40k concurrent users with persistent connections, a little depending on how you define concurrent.. Regards Henrik
