Hi! Im trying to host a Forge 1.12.2 minecraft server, the problem is that whithout any gamechanging mods the server TPS drops from 20 to 3 in arround 1-5 seconds of flying in spectator at max speed. The only mods that i have are LagGoggles and Something that messes with the TAB. [Screenshot] The problem is that even there are low tps forge isnt taking more cpu? Minecraft does not support multithread right? Well, none of my cores are +15% of charge while running the server, its something with forge that isnt taking resources because im able to support an spigot/paper server whith more than 50 plugins (mods are heavier, but remember i have 2) that stays between 19-20 tps while 3 players are flying with the spectator at max speed. Bat file: java -Xms8G -Xmx8G -jar forge.jar nogui pause I have tried whith this -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M but i couldnt tell the difference. My PC specs: Ryzen 5 3600 16 Gb DDR4 3200Mhz Server running in SSD. I dont know whats causing that, but its clearly impossible to play.

This isnt my first time hosting a forge server but im having a weird problem. If i start the server double clicking the server forge jar everything works fine, a server with 500mb of ram with the ulgy minecraft server gui. Now, if i try to execute the server with a CMD because its best that using the minecraft gui and you can set more ram, the server crashes instantly, no crash reports, no logs.
