I want to use scoreboards in my plugin. So I found the scoreboard.getPlayers() method and so I used it. But my plugin caused heavy lags on the server, so I found out, that these lags were caused by this method. It takes about 2 to 7 seconds to execute this method. I'm using now scoreboard.getEntries() method, but it seem to be bug, that the other method causes so much lag.
