All about the java args?

[Bi0Ph34r]

Anyone know how to exactly use java args on a mc server I read a lot of this and that, but has anyone know for sure they are needed. For example here are mine:

-Xms2G -Xmn512M -d64 -XX:+UseG1GC -Dfile.encoding=UTF-8

but is xmx and xmn really needed

I would need -d64 and the utf=8 for me being on a windows

but does anyone actually test and see if they are needed or what is best?

I use amp panel which has a spot for max allocated ram so I don't use xmx as developer stated I don't need to with panel having a max allocated ram (max heap size) option.

Also what about how many people can be hosted on so much ram, I see so many posts on this. One guy had tested 40 people on 2 gb ram with 30 plugins or so with no lag. When I start one server up which I allocate 2 gb ram it starts off using 1gb ram to to stay online so how many people could you host say off 1 gb ram?

Also I have a mc-32 ovh dedi.
