I noticed that repetitive deployments increase the CPU load. I noticed it first on 0.19.5 but it still holds for 0.20.2. Stopping and starting Node Red reduces the load to a normal level.
I did several (like 20 to 30) deployments during 2000 and 2300.
I'm running NR on a Raspberry Pi 3 running Raspian, Node v10.15.0.
Is this a known behaviour?
