Save all data very slow!

Hello.
this is the 5th time this software has been installed. I thought I didn't do some settings correctly, but every time the software runs very hard/slow. the entered data, customer, product, service, trivial settings, are very difficult to save. the software runs on a dedicated hosting server with php 8.1 and I have xdebug disabled. any thoughts or opinions? thank you.

I also run into this problem. It is clear that the problem is not with the hosting server that I have, as other applications work without problems. Can anyone help to increase the performance?
