Yall need to make this game not single threaded

This effects all versions of minecraft since the game runs on all threads when u guys can rewrite the game to make it multithreaded without effecting behavior of tnt,ticks

Like for example a player has too much data ur server needs more and more hardware 
Im tired of playing this game and seeing servers lagging thats why nobody plays this gamemode u guys have to do a tutorial on multi threading since other developers have found out how to but still some features like minecraft tnt primed is really laggy when we wanna play a gamemode that uses a lot of ticking and its so stupid that we cant have the right amount of tnt for certain cannons too work which is really fun.

I honestly dont know why u guys cant limit how much tnt is active on 1 thread I pay like 500$ a month for software u guys dont understand how much that is sorry my grammar is a bit off but ye u guys need to rewrite minecraft so we can do cool things without lag like raytracing needs to be optimized I havent played vanilla minecraft in like 4 years because how unoptimized it is
