Client taking insanely long to do what its doing?

[Zortex]

I Recently made a aura kingdom private server to play on with my friends but when i finished and started the client it started doing stuff to the files as it usually does but its taking Extremely long, Its been 4 hours and its not even gotten to 50%, is there a reason for it being so slow?
