Server Requirements, commands, and known issues

Server requirements

1. Refer to http://canihostaminecraftserver.com/ to see whether you should host a server, based on your internet bandwidth.
2. The more memory your computer has, the better. It's recommended to have more than 2 GB, that way plenty is left over for the operating system, and you have the possibility of allocating more to the Minecraft server.
3. Minecraft servers, as of beta 1.8 are only capable of using a single processing core. However, multiple cores can increase performance if your server is performing other functions.

Server commands and known issues

See the known bugs page for known single/multiplayer issues.
Special note: Atheros and Realtek network adapters are known to not work well with Minecraft in general. If you experience a total loss of internet (requiring a reboot), or constant disconnects, check and see if you have either brand of network adapter installed. If you do, you can try updating the driver for the device directly from the manufacturer. If a driver update does not fix the issue, the general solution is to buy a new adapter (anything from Intel is recommended as a replacement).
The server commands page has a list of useful commands.
