CPU Limit question for Etherpad

[sparkwise]

We recently ran a load test of our systems, and saw something a bit surprising with Etherpad. Under significant load, the CPU utilization maxed out far below the "Max CPU" line set based on the CPU limit set in the Resources tab. Is possible that the Etherpad app (or Cloudron) isn't taking into account the number of cores available, as described in the docs?

So etherpad is a nodejs application, which in turn is only single threaded. This means the main process of etherpad alone will only max out one core at all times.

Got it. Thank you.
