Basically any significant Java software uses disproportionate amounts of RAM. My server can easily run a web server, database server, ftp server, memory cache, etc., times a few copies because various containers have their own web server or whatnot, all at the same time. But a single copy of Minecraft is too much, even when everything else is shut down.

That's why I struggle with the server: it's written in Java. Other game servers don't seem to have this problem. If the network protocol were all, that'd be great
