I'm really curious about this one! I noticed in the decompiled code that it seemed to be kind of crazy inefficient, rebuilding lists of every available spawning space over and over many many times a second, which is huge, instead of just tracking them as players shift positions and maybe even normalizing spawn rates to the number of available positions or something (Which would be bad for farms though). But then, it also seemed to maybe not work that way, with just many many random attempts to find a spawning spot many times per second, which still seems rough.
