So I've been trying to rebuild my server's database using UUID's. First, I tried to use the inbuilt UUID api, in Bukkit, but when I checked for it, I realised that it was not the same, as all of the other UUID checkers out there (e.g. fishbans and other tools). So I moved over to http://dev.bukkit.org/bukkit-plugins/identifierapi/ but whenever a player logs onto the server (This is where the server gets all of the data of the player), the server then lags for about 1-2 seconds, while it's getting the UUID which is a quite a big problem. So I'd just like to ask if there's a lot more simple way of doing this, which wont make the server lag, whenever it checks for the UUID. Thanks.
