I’am still having problem with slow post for new topics and it’s even worse now.
About 20 sec to post a new topic. Reply around 1 sec which is fine.

But, the actual post takes around 1 sec but something is happening in the background that takes another 20 sec before the page load is done. I can verify this by opening another browser window to see the new topic.

All plugins disabled except bbpress.
Wordpress 6.1.1
Theme 2021
