@AdamStuartSmith @smallcircles @dinotoyblog @blog@animaltoyforum.com @blog@monstertoyblog.com I suspect this is a WordPress problem more than an ActivityPub problem. Each request loads the entire WP framework and theme and makes 10–100 database queries, depending on how many plugins you use. I've seen WordPress servers grind to a halt just because they were receiving a huge number of requests for files that do not exist, and WordPress’s 404 page runs the same full code path.

Like others mentioned, caching is probably the fix.

Hey, @activitypub.blog, do you know about this issue? ^ @AdamStuartSmith
