Question TPS Issues On My Paper Server [URGENT]

[AdamJae]

Hello!

So I've recently started up a MC server and I have been trying to tackle TPS issues for ages now. I have tried to eliminate as much issues as possible with performance guides and so on, but I still haven't got to the bottom to why my server's TPS gets melted when 15+ players are online at once. I know spawners are a big issue but I have hammered down on the mob spawn and max mobs per chunk now. However, I am still getting TPS issues... I will link below a spark report and a timings report I have made.

Server Specs:
CPU - Intel i7-8700K @ 3.7 / 4.7Ghz (6c/12t)
RAM / MEMORY - 32GB DDR4 @ 2666MHz
Default storage - 512GB NVMe SSD

Spark - https://spark.lucko.me/sUhqmAWt9H
Timings (with low players online) - https://timin.gs/?id=c5c7bc02216842008bd3776b10b251a1
Timings (with 15+ players online - TPS drops shown here) - https://timin.gs/?id=03c874d8eeb942b3838b8acbfb2fb9e9

I appreciate anyone who responds to this thread, thank you!

There still seems to be quite a few regions with high amounts of mobs, some regions have over 2 000. I'd inspect these regions and see where all these mobs are. It might be that someone has a large mob farm, or that a bunch of mobs are unable to despawn due to holding items. If you reduce the amount of mobs in these areas, I'd expect your TPS to improve.
