So with the recent launch of Minecraft 1.13, I've decided with 2 more friends to set up a server in order to play together.
In the past, I already used plenty of server and I never had problem to allocate more RAM (usually I set up 4GB). But with my 1.13 server, I can't allocate more RAM even if I used the same code for my previous server.
I have 16 GB of RAM on my computer. My server is stuck with 1.5GB average. It is as if my server think I have a Java 32bits even if it's not (I have installed Java 64bits for sure). This cause some lags when we are generating the world (the server can't keep up).
Looking forward to see your thoughts !
Here is some picture of my Run.bat and my console :
