Some additional info. I have been periodically reviewing the 'Quality of Service' values over the past couple of days and I am finding a large variance in the value. My original post had a value of 209ms but I have seen the value drop down as low as 16, It's not consistent (and perhaps that's understandable if there are lots of users on one POP), it can maintain a value for an hour or so and then jump up or drop down. I've looked at busy and quiet times of the day and it's inconsistent. I also cannot the value to the performance hit. When it's down at 19oms, it's a slow to load pages as when it's around 150 or above.
