for you to be posting this question at this hr, means you're trying to nif when theres more niffers around so
what else do you expect...>_>
either way, its fine for me, and i dont see anyone else complaining. check if its client side lag, like when you're running something on background (same for malware). if not, might be your internet service. but for the last you'll have to contact your ISP for more info. Adding too that if you live too far from the server, the lag can be caused from this too. Lastly if in area its a peek hour of people acessing the net, the server might get more busy adding to the lag...... but anyway
too many reasons
