22.2.1 is very slow

[DmDS]

after upgrading to 22.2.1, nextcloud is very slow. after opening the page, everything is fine. after 1-2 minutes (possibly inactivity), the load on the web server increases greatly during rendering (I tried apache and nginx. php 7.4 and 8.0. and installed nextcloud from scratch). the site loads very slowly. if you log out of the account and log in again or restart the browser, it starts working fine, but after 1-2 minutes everything slows down again.
on a test machine with one user, this is still fast enough. in the working environment, it slows down much more.

I copy this! Updated by "test cloud" and the "felt performance" dropped by around factor 10! Switching to a different app in the menu takes around 5 or more seconds, while it was "immediately" before.

I also see that with every action two php-fpm processes are spawning, each taking around 50% of a CPU core (my VM has 12 vCPU) which does not happen in 22.2.0.

I've rolled back the snapshot and I'm currently retesting. But for now I explicitely warn anyone from upgrading to 22.2.1 in production environments!

PHP: 7.4.25
Apache using php-fpm7.4

Confirmed on a second instance!

Some time measurements to compare on the instance before and after the upgrade (from clicking until all page elements have been loaded):

Changing from files view to the room overview of BigBlueButton:
22.2.0: 1,4 sec / 22.2.1: 16,7 sec

Back to the file view:
22.2.0: 3.2 sec / 22.2.1: 27,3 sec

To calendar view:
22.2.0: 3,8 sec / 22.2.1: 30,2 sec

@szaimen Pulling back immediately the 22.2.1 release is a wise decision! ;-)

Are there any problems with 21.0.6? Can anybody confirm this?

[szaimen]

21.0.6 should work fine as #29380 wasn't merged yet

[tdoerschel]

I can confirm this on apache 2.4.51 and PHP 8.0-FPM

Patch forward is at #29682

@nickvergessen Will there be a bugfix release (22.2.2) in short term, or what is the plan?
