Just upgraded to Docker for Mac 2.4.0. Among the release notes is an item “Docker Desktop now uses much less CPU when there are lots of file events on the host and when running Kubernetes”.
Typically I have seen Docker anywhere from 60-100% CPU. I installed the update and reset the disk image to start fresh. With nothing running, but K8s installed, I am indeed seeing what looks like a better idle CPU usage for Docker for mac – round about ~40%.
However, once I install my convox local rack (with no apps) 3.0.42, it pretty quickly jumps to more like ~60-80% idle.
Are there any tunables here? Any things that can keep local convox from chewing up CPU all the time?
