Push notify app does not reduce load on server

Hello I have same problem in two nextcloud installations with a lot of clients. There is a lot of profind request on the server and so load is very excessive and users can’t use web interface.

I installed notify_push but I don’t seen change.

Nextcloud 27.1.9
PHP 8.2
Linux debian installation.

What are solutions ?

Did you install the notify push server like it is explained on the github page you have linked?
They also provide information about logging, where you might find some errors if not installed properly.
