Tip: If you want to spare more memory, you may set the -Xms parameter even lower, say:

java -Xms32M -Xmx512M -jar minecraft_server.jar nogui

The parameter controls how much memory is reserved on startup. Your server will start with 32MB RAM and whenever it needs more memory it will allocate some until it reaches the maximum of 512M. However, this will result in a little slowdown whenever the allocation is done.
