[erlang-questions] How many processes do you run in your BEAM?

I'm curious how many processes people have luck with running in their BEAM vm.

The Logplex cluster at work is running R16B02 with the following stats: (rq = run queue length, procs = number of processes, otp = version number - these figures are reported machine by machine every minute aggregated over 15 minutes)

avg(rq)   avg(procs)   stdev(rq) stdev(procs) max(rq) max(procs) mode(otp)
97.792722 50676.159810 74.305638 185.676264   267     50963      R16B02

Are there known scaling limits for the schedulers? Are there guidelines for common problems (our avg(rq) becomes greater than some threshold, or as a ratio over avg(procs) it crosses a threshold)?
