0.3-0.6 Sustained Time Dilation normal?

This sim I am located in (Archan) Has had dilation fluctuation rapidly between .3 an .6 for the last 18 hours. Normally, it is a steady .91 -.94 with about 41fps. Now, it is impossible to move in the sim. Granted, it is a club and has a lot of people and objects, but I have not added anything new to the area in the last few day so I'm at a loss for this sustained horrid sim performance. i've seen this happen before, for brief periods of time, and it always seemed fine after a linden reboot the sim. Today, however, i called a linden and she told my my colliding objects were causing the problem and refused to reboot the sim. I have not changed or moved any objects, so I fail to see how they should impact sim performance today when they did not yesterday.

I've been having the same problem in other sims.

It's all coming down children. Wear your helmets.
