The C10k problem ^[1] is the name given to a limitation that most web servers currently have which limits the web servers capabilities to only handle about ten thousand simultaneous connections. This limitation is partly to operating system constraints and software limitations. While there are some specialized web servers that can handle more than ten thousand client connections, most web servers currently handle at most ten thousand clients simultaneously.

[edit] Nginx and C10K problem

"Nginx is one of a handful of servers written to address the C10K problem. Unlike traditional servers, Nginx doesn't rely on threads to handle requests. Instead it uses a much more scalable event-driven (asynchronous) architecture. This architecture uses small, but most importantly, predictable amounts of memory under load. Even if you don't expect to handle thousands of simultaneous requests, you can still benefit from Nginx's high-performance and small memory footprint. Nginx scales in all directions: from the smallest VPS all the way up to clusters of servers. " ^[2]
