It does sound like each server is its own process. I think you're correct that it would be a little faster if all games shared a single process. That said, then if one crashed it'd bring the rest down.

This is one of those things that might take weeks just to _test_. Personally I suspect the speedup by merging them would be pretty minor, so I think they've made the right choice just keeping them separate.

I've found context switching to be surprisingly cheap when you only have a few hundred threads. But ultimately, no way to know for sure without testing it. A lot of optimization is just vibes and hypothesize.
