Server & Performance guides
Minecraft guides filed under Server & Performance.
Whitelist, ban and op: the server commands that behave differently than you expect
Whitelisting does not kick players already online, /ban needs a reason to be useful, and op level matters more than the op list. The details that bite server owners.
server.properties: the settings that change performance, and the ones that do nothing
view-distance and simulation-distance are not the same lever, and one of them is where your TPS goes. What each setting actually costs, with sensible values.
server-icon.png: the exact requirements, and the management API nobody uses
64x64, PNG, at the server root — get any of the three wrong and the icon silently does not appear. Plus the JSON-RPC management API that replaced screen-scraping the console.
