Well, too many processes just waste time in swap and longer run times. Once you use up the limiting resource, more processes may lower throughput and increase latency. It is like if two people show up to dry 2 loads of clothes, and only 2 dryers are open. If one guy says, go ahead, use both, he is not delayed and the other guy is there half the time. Overloads belong in queues. Red lights on downramps keep speeds up. Maybe it will run faster if you lower it. You need precise measurements and then you can move it a little at a time, to see.
