Well, there's a ticket out there for "thousands of collections on a single machine", although this is waaaay out there. I often see 10-20 small cores on a 4-8 core machine if they're reasonably small (a few million docs). I see a single replica strain a 128G 16 core machine if it has 300M docs....
Which is a way of saying "ya gotta test with your data/query mix"..... Wish there was a better answer.
