Can a 2GB Minecraft server hold 32 players with plugins

Generally, a 2 GB server would be able to hold 32 people if they were doing nothing. Even under these circumstances though, the volume of data involved would swamp this server.*

* There are many other variables that determine how many people a server can hold. Assuming a good internet connection, a more practical number would be a maximum of 10 - 15 players. This configuration would cause some lag, but would be less likely to crash.
