For those interested in cuberite prefromace here is a chart I made for RAM/Swap (Bench marked On Nano Pi Neo - Raspberry Pi clone)

System IDLE
2.3% cpu
68mb ram
0 swap

Cuberite (No players)
~5% CPU
204 mb ram
0 swap

Cubrite (1 player)
36% CPU
206 mb ram
0 swap

Load time around 35-45 seconds

We should really find or create a bot to simulate multiple players. That way we can also get a clear picture of how the server works under heavy load.

I think pycraft is a good tool for your idea. I tested it by connecting around 300 clients to the server, with the help of threading. It's also possible to send chat messages and commands to the server.

Just saying to @DarrenRainey, any ram usage you can get via htop (or the underlying /proc file system) it is not quite right, because you can hardly measure the optimizations the system does for you.

And another question, does the cpu usage mean 100% = 1 core totally busy or does 100% mean all Cores (if so, how many?) are busy?

Yeah ill do a better benchmark later but you can still see a major difference between Cuberite and craftbukkit.

The cpu usage is the total of all 4 cores
