My machine specs:
iMac (Retina 5K, 27-inch, 2017)
Processor: 3.4 GHz Quad-Core Intel Core i5
Memory: 16 GB 2400 MHz DDR4
Graphics: Radeon Pro 570 4 GB
Very recently I have started noticing that all cores suddenly report idle for a moment and then go back to full use. Quite similar to garbage collection in a JVM. Please see the attached CPU History picture below. Note how at one place all cores were being fully used but they suddenly black out:
This is a recent phenomenon on my machine. Can someone confirm that it happens on their machine too?
If not, would someone help me identify the cause behind it.
