Huge lagg problem

Hi,

This weekend I've been having big lag problems, and i can't do anything about it :/

I've tried everything, and wasted over 2mils on DCs on dungs, i get DC all the time... T.T

Anyone know how to solve this or atleast lower the ms (lag)?

Help would be really appreciated (did i spell it right? xD)

I wasted like 5mill for lag then mob get over 45. Its just the event and stuff. You know how holiday + weekend XD
