So first off, I just want to say that Shared Hosting sucks and to avoid it all costs if you're running more then one WordPress install. I learned the hard way, and now I'll be soon venturing out to purchase a VPS.
So... my issue is interesting. For the past few months all of my websites (and clients websites) have been incredibly slow. At random intervals throughout the day my CPU would throttle and my shared hosting account would become 'limited'.
So during this last huge spike 3 hours ago (3600 seconds) I checked processes and FINALLY saw a clue to which install may be causing this. There was an anonymous WP cron job from said WP directory that was taking up A LOT of CPU. So I installed the Core Control plugin and started looking at all of the Cron tasks.
Once Off - wp_cache_preload_hook - Hooked functions: wp_cron_preload_cache() Reoccurring - Every 10 minutes - mwp_backup_tasks - Hooked functions: mwp_check_backup_tasks() Reoccurring - Once Hourly - wbz404_removeDuplicatesCron Reoccurring - Once Hourly- jetpack_clean_nonces Reoccurring - Once Daily - mwp_notifications - Hooked functions: mwp_check_notifications() Reoccurring - Twice Daily - wp_version_check Reoccurring - Twice Daily - wp_update_plugins - Hooked functions: wp_update_plugins() Reoccurring - Twice Daily - wp_update_themes Reoccurring - Once Daily - wp_scheduled_delete - Hooked functions: wp_scheduled_delete() Reoccurring - Once Daily - wbz404_cleaningCron Reoccurring - Once Daily - cron_load_ads
about a quarter ways down the page I started just seeing about 200 'Once Off' tasks with this hook to 'run'
publish_future_post - Hooked functions: check_and_publish_future_post()
Now mind you, I have no pending or scheduled posts. Could this be my issue? And if so, what can I do to fix it, and what would have caused it? I've been doing research on this crap for the last few weeks and I'm incredibly clueless on what to do.
