I have a dedicated server with 64G of RAM, XEON 5640 x2 16 core 24 thread, 24M cache running Centos 7 php 7.2, MariaDb 10.2 with DirectAdmin and Litespeed. I've installed Moodle 3.9. We have 270 users which login to website at 8 AM. in the 9 courses we have a Bigbluebutton plugin for separate groups and recording enabled.
At first it was fine but after 4 months as it has a lot of recordings in it (about 200 in one page), it crashes the server.
The only thing that surprises me is that, when I use Bigbluebutton plugin, even when it is only me, (late at night when the students are not participating in the classes) it uses 100% of on of the threads and makes the server really heavy.

as you can see I have a powerful server which can handle thousands of users simultaneously. Why should the plugin drain the cpu so?
this is when there is very little site visits. When only me using the bigbluebutton plugin:
this is when we have 250 users participating class:
should I delete the recordings?
