1.14+ servers are horribly optimized.

1.14.3 is so horribly optimized, that i need 24 Gigabytes of ram for a few players on my server, and my CPU is always maxed out, just to support a multiplayer environment. Compared to the 2 Gigabytes or ram needed for 1.12.2 and barely more then 10% CPU usage, why is your server software so badly optimized? What is inside the new versions that consume so much CPU power and RAM??? Your'e making it very hard for private server hosts to host their own servers by demanding lots of CPU power and RAM.
