Description of issue:

   Hello, I have been having some issues with TPS and memory on my 1.15.2 Minecraft server. I have tried optimizing chunk loading (as by timings this is shown as a major cause of TPS loss.). But I am still having tps dip as low as 15 with only around 12 players online. The server is running on three dedicated threads and 10 gb's of ram. I really could use some fresh eyes to take a look at this. 
   Additionally, I have also been having issues with a supposed memory leak, my ram usage will just continue to climb until the server crashes, I have disabled saving advancements, and I am now using the aikar flags which were recommended to me. But I am still not seeing ram return to an idle level even when there is no one on the server.

Here is the most recent timings report (as of 22:13 the 15th of July) https://timings.aikar.co/?id=9dbda1f9463d47da86dcc2c38dd71840 To me this shows that it is chunk loading, but if I have the world pre-loaded, should it still be effecting tps this much?

Additionally, I am running a 1:1000 scale map of the earth on my server, which I have pre-loaded for dynmap. It is a massive 40k long world.
