For several weeks now, although I did not change any settings it takes an extremely long time for a sim and its guests to rezz. Whatever the viewer I use, the result is the same. I tried with a iMac running Lion with Radeon graphic card and with my basic pc with its integrated graphic card. My internet connection is dsl with an average higher than 30 Mb/s download speed. The puzzling part is that until 6 weeks ago I had no problem whatsoever with either machine.
