Jobs::PeriodicalUpdates is the cause of high CPU (over 100%)
When we check: sidekiq/scheduler/history
I see, Jobs::PeriodicalUpdates reached 79 secs. Causing the CPU to increase, users accessing the website are out.
Does turning off Jobs::PeriodicalUpdates have any effect? How to turn off?
And, Jobs::AboutStats ; Jobs::DestroyOldDeletionStubs ; Jobs::DirectoryRefreshDaily ; Jobs::EnsureDbConsistency
also causes CPU to go high above 100%
I’m not an expert to analyse this, I see two settings mentionned
automatically download gravatars, I don’t thnink it would explain a high CPU usage
rebake_old_posts_count this one is now hidden, but maybe you did set up a lot of old posts to rebake every 15 minutes months ago. It would explain this cpu usage a bit more
You can’t turn it off. There have been changes that require a rebake. If you have enough resources you might be able to adjust things to improve performance.
