Sticky posts issues when Redis cache is full (cont’d)

Yes, that should work, but be sure to test it with a persistent object cache enabled.

Are you able to post the redis-cli MONITOR logs for the wp_update_post() call? That way we can analyze what’s causing the slowness.

Speed difference is 20x.

Actually the slowness has nothing to do with a object cache, it’s the same when it is enabled or disabled.

I guess some plugin is causing it, even though $fire_after_hooks parameter is set to false in wp_update_post call.

Any idea how to identify the bottleneck? Tried https://github.com/WPProfiler/core but for some reason it didn’t work properly with this Ajax call.

You could use XDebug to see what’s firing when wp_update_post() is called. Or turn of plugins one by one to find the culprit.

‘transition_post_status’ action is the cause.

Need something to measure execution of hooks in production without turning off plugins.

Also found https://derrick.blog/2020/01/15/debugging-wordpress-hooks-speed/ but it doesn’t work properly.
