FOSS gamedev and creative worlds

Hi all,

After setting up my own private server i noticed that the memory usage at server startup is about~20MB. After logging in and playing it rises to ~300MB. After i logout, the memory usage slowly declines over an hour to ~85MB. Why does it use more memory after i played than before? I'm not trying to nit-pick, just curious. PC specs are Debian 8 "Jessie", 512MB of RAM, Core 2 Duo e8400@3Ghz, minetest 0.4.14dev. Thanks!

Well, I realized that the map/textures are cached. Not a real issue, just a noob mistake ;) Any admins feel free to remove this topic!
