CPU load cannot be high even with a small number of users!

Hello, I have a problem with high CPU readings up to 220% already in a conference with three or four users. If a conference takes place via a mobile application before the CPU is used, even with a single user, it immediately grows to 80-100%. Is there any way to fix it? Is it possible that Jitsi Meet does not always work in p2p mode?

How many CPU do you have, and what spec are theirs?

I have a similar situation。When I start 80 active one-to-one conferences in jvb Process,CPU can reach 20% with eight-core Intel ® Xeon® E3-1230 v6 @ 3.50GHz CPU, but compared with https://jitsi.org/jitsi-videobridge-performance-evaluation/ , performance can
only reach 10%, I wonder if it is my configuration problem.
