Hi @Karl_Svozil,
odrive checks for updates roughly every 30 minutes or so. Everything else done on a periodic basis is generally between 15 minutes to an hour.
When you see it spike again I can take a look at the diagnostic and see if anything stands out.
There was a suggestion here that lowering the CPU priority for odriveapp can help prevent things from getting too bogged down when things are running hot, if you want to explore that as a workaround: Decrease CPU priority so ODrive doesn't interfere with other processes
