The most rampant reply went something like this: "Use FreeBSD. Linux has traditionally had problems with its TCP/IP stack, especially with lots of connections." There was one mention of kernel accept buffers that might be too low, but I wasn't able to actually find the tunable in the kernel source anywhere. -- Michael J.
