127 Linux performance with pop
New, NormalPublic

Description

My servers are generally low pop, but last week I had a spike in pop.

When my server hit 18 players, fps went from around 7000 to 1.

This was seen on Hashima, I tried to produce the issue again on my own map but never had more than 13pop so the issue was not noticed.

System is a Ryzen 9 7950X
My old window 2022 box handled the exact same server with 38pop and 20Q no problem on a Ryzen 7 5800x

I had 15-20 players on my pve server when Hashima was released, didn't have any issues with it back then under linux. For me it only got worse with 1.28.

Also AI performance under linux went from not-so-good-at-all to not existant. Spawning AIs makes the server go down to 1-2 FPS now, while the same thing under windows just works perfectly fine.
