I think equally important (to sites that serve alot of traffic on production boxes) is the value of NR_TASKS in linux/tasks.h. The default allows 256 simultaneous requests, which isn't a whole lot of procesess for something like a busy apache. I think it would be great if this value could be set in /proc/kernel/max-tasks or something like that, rather than having to edit the source and recompile. Maybe this has already been an idea though. It seems like some servers like squid and news servers require lots of fd's with high load, where as you pointed out, daemons like apache just fork processes, so those have the other need of increased NR_TASKS.....
