   I thinking of uninstalling the excellent #Wordpress #ActivityPub Plugin and defederating my sites from the #Fediverse. For technical reasons only. CPU goes through the roof when new posts are boosted for the first time, causing 508 errors.

   Does anyone else suffer from this problem and have any suggestions to lighten the load?

   Maybe I’m overreacting and should just live with the minute or two of daily downtime?

   I have Litespeed cache installed.

     @AdamStuartSmith @dinotoyblog @blog@animaltoyforum.com @blog@monstertoyblog.com so you have the issue even with the lightspeed cache?

     @AdamStuartSmith I will put it on the backlog.

     idea: an option to chose between different scaling/load levels.

     1. publish as fast as possible (high load)
     2. reduce bulks and increase pauses between sending
     3. take your time ☕️

     @AdamStuartSmith is this "only" a problem when you post new things?

     so there is always the option to tweak the scheduling, to not send all pings at the same time. the only downside is, that this can take some more time until every of your follower receives the new post.

     @pfefferle Exactly. Maybe there are there some Litespeed settings I could tweak?

     Thanks for your interest and help.

     @AdamStuartSmith phew... the load as a result of boosting is hard to intercept: https://ar.al/2022/11/09/is-the-fediverse-about-to-get-fryed-or-why-every-toot-is-also-a-potential-denial-of-service-attack/

     @pfefferle Only when I post new things, but for each new post there are two CPU peaks associated with CPU faults. One when it is first published, then a larger one later when I (or someone else with a moderate following) boosts it directly on Mastodon.

     Happy for pings to take their time. Thanks for looking into it, I’m also working through the suggestions as far as I’m able.
