Minecraft usage

Post by .=QUACK=.Major.Pain »

Wondering what is normal for a minecraft server.
Ours is running at 400-500mb empty, and seems to increase by 200mb per player.
CPU stays about 1-10%, but spikes a lot up to mid 20's and sometimes much higher.

Running it on a single core system right now with a l4d2 server and ts3.
Procon also runs there as well, but it is idle with server being empty.

Changed to a SSD drive, but things seem to get worse stat wise.

I don't know if it's related to the drive problem that you mentioned in your notice for our server.

The game only needs something like 30 MB per player above a smallish base amount (like a few hundred MB), but uses the rest to cache loaded chunks, so you'll have a difficult time determining what you need to assign the Java process. Keep an eye on the CPU usage and how the server feels in-game and use those to adjust the server if need be. If you run plugins, make sure that they are optimized, as well.

The kids have been complaining alot about the lag.
Not sure if I should jump back up to a 2-core, or if that will even help.

CPU bounces around - idle it's at 1%.
With players it mostly stays under 10%, but can spike.

Right now the server is empty, and it's running at 592/1024mb

Would running multi-maps create more load?
They run the multiverse core to create more maps.

That can create more load, yes. Each chunk loaded takes up RAM, which means that if you have say 6 players all standing next to each other, they are all going to be in the same area without extra chunks loading as much. Take those same 6 people and have them out running around in different areas, suddenly a lot more chunks will be loaded and taking up RAM.

In the case of multiple worlds, especially world generation which can spike CPU, that load can increase quite a bit.
