I tried your plugin just to try it out of curiosity. I then uninstalled and deleted it. Trying to optimize and fix high CPU usage in WordPress, I have come to find that these Cron Jobs were left. I am fairly certain they are yours and running hourly. Yes I know the action is none but I am assuming WordPress still tries to run them causing the CPU usage nonetheless.
- Are they indeed your jobs?
- You might want to update your uninstall to take care of these also, maybe get “AI” to do it for you 🙂
