FiveM server runs verry bad on another host system despite better hardware

Hey there! I have following problem:

My fivem server is running in a debian 10 lxc container.
I have two host-systems, on one of them the server performs well, and on the other much worse, although he has more “power”.
On my host-system with an i7-6700 the server runs without any problems. However, on my second host-system with an i9-7920x, the server runs verry bad. => “server thread hitch warning: timer interval of 1989 milliseconds”

On both host-systems, the container is located on an ssd, both systems have relatively fast ddr4 memory.

kind regards

This sounds like something happening to script code- the profiler (see the docs page on it) may help find the issue behind this.
