hey,
can the performance of this method be improved?

Performance is better now but it is still overall bad:

What's your setup? The usage shouldn't be this high.

It's on a server with 20+ players so I can't check for an setup.

Then it's hard for me to just increase the performance of the method.
It's as well performing as I could make it at the time, and I doubt I can change anything about that without actually seeing what the problem looks like in-game.
Please try finding out the place that this high usage is originating from.
