So im making a minecraft server, how do i give it more ram for less lag?(rn i cant even break blocks really)
In your start.bat change the -Xm values:
java -Xmx4096M -Xms4096M -jar minecraft_server.1.16.3.jar
im not using bat.
If you are using a hosted server then you have to increase it there
Otherwise use a startup script that matches your servers hardware.
