We are changing the the UserPointLevelCache timeout from 1 hour to 12 hours. This will reduce the number of times that point level calculations are made for each user, and the resulting reduction in cpu load is expected to improve system performance. It also means that when you post to a community or are awarded points for a helpful or complete answer, you will not see your point total updated for up to 12 hours. I expect this to be a temporary change until we have stabilized performance, and then we will return the timeout to 1 hour.
