> Testing 10 reloads every second really distorts the numbers, assuming a reload every hour, or every few hours is more realistic.
It depends on what you do. I've seen shops (successfully and, IMO, correctly) scaling AWS instances for services with a threshhold of every fifteen minutes, and I've seen Mesos clusters dynamically spinning up web instances much more nimbly than that (think every two minutes under spiky load--the instances would come up in five seconds, so it didn't hurt to down them).
Sure, but if it doesn't work there, I don't trust it to work if, say, a piece of my scheduler goes nuts and suddenly is upping and downing containers every few seconds. The problem remains, it's just not as acute and still must be fixed.
