A freshly started server with nobody connected used about 1 GB of memory. That is an idle figure: memory use grows with more players and a bigger explored world, so check it on the Overview page with players online.
Check your own usage
Open your server's Overview page and look at Usage, then the RAM tab, while players are online. An empty server tells you little, so read it with players on. See How to read your server's usage graphs.
Tips for a healthier server
- A higher maximum view distance for players needs more RAM, so keep it moderate on small plans (the setting is MaxChunkRadius in data/serverconfig.json).
Change plan
If memory keeps reaching your plan's limit while players are on, move to a bigger plan. See How to change your plan or billing cycle.
