Very long page open and/or module query

Hi,

I've noticed very very long times in bx_profiler.log

Here is just a few:

How can this be corrected or how to troubleshoot?

Our server is running Ubuntu 20.04, Apache ver. 2.4 with php7.4.fpm and MySQL ver. 8.0.22

Any suggestion please?

Kind regards
Mayki
