I'd like to add two things:
1. There's a branch (#3151) which allows you to use any extra RAM as a cache to speed things up, but as of now we decided not to merge it because it complicates codebase maintenance and there are higher priority things to do. So it currently isn't part of Cuberite and as others have mentioned, right now, Cuberite uses as much as it needs.
2. You can still encourage Cuberite to use more RAM by tweaking the UnusedDirtyChunksCap setting in settings.ini, the higher, the less frequently Cuberite will release chunks under load. If you set it ridicolously high, chunks will only be released once every 5 minutes. Note that this setting will probably have no effect under light load.
