This is not an issue with the database connection.
The plugin is REALLY slow on startup.

READ THIS PART PLEASE:
This was not an issue on earlier version. It takes about 2 1/2 minutes for it to load up! Which is a really long time for any plugin.

I'm using Spigot 1.8.7 & BanManager v5.6.0.

Don't open duplicate issues, it's very annoying. Duplicate of #504
