Server TPS Lag

[tenshiku]

So we've currently hit the max amount of players on the server (60) and people are wanting us to up the player amount, but with how the server is handling with the TPS I don't think we're able to do that right now. I was hoping if someone is able to help me and figure out whats causing all this lag.

We have both SSD and HDD, I believe the server is currently on the HDD

First thing I'd try is getting on the SSD. Lots of entities in that report. If you can temporarily put the server on Paper then do a timing there it would be easier.
