Hi! I don't know where else to report this, didn't find anything useful on the internet, so i decided as a last try to write here.
My issue is that when my server's GC frees up the ram, or even just while running, it gets insanely laggy sometimes. Sending the warnings "Can't keep up! Is the server overloaded? Running 6980ms or 139 ticks behind" like this. I gave the server 16GB ram, but as i noticed its not using my cpu fully, only a few cores.

Here are the specs:

CPU: AMD Ryzen 7 5800X3D
Motherboard: MSI B550-A-PRO
RAM: 2x16GB Corsair Vengeance 3600MHz CL16
GPU: AMD Radeon RX6600XT
SSD: Apacer AS2280Q4 1TB

I really hope this is the right place to post this, and hoping to find a solution.

The lags on the normal server were much worse than on papermc, happened every minute, rather than 2-3 minutes on paper)

Performance logs of the original server file attached, every other information is the same
