The new Raspberry Pi 2 has got twice the RAM and a load more processing power, so will it make a better Minecraft server? The old Pi made an adequate Minecraft server providing you only had a few players and you kept the view distance low.
I tried both the vanilla server and a spigot server, both similar results, both performed reasonably well. I was only able to test with up to 3 players but it worked well under those conditions.
