I am generally curious, how many connections could CF realistically handle, in terms of it's server's socket connections?

I ask because I am doing some load testing on a c++ socket server I'm writing (totoally non-mud related) and am wondering what sort of numbers the mud server could physically theoretically handle before connections started getting blocked (as a comparison); I'm hoping to get an answer independent of what overall program memory might allow, for simplicity's sake.

Also, what platform is CF run on?
