Is this a new issue or something that has been going on for a while? If new, I would contact them, but if it has been going on a while, it's a Blackbaud issue that most companies have. I have used Raiser's Edge for a long time and noticed that there is a speed issue once you are in a hosted environment. Whenever I had to do something large, I did it after hours or Friday late afternoon, during off peak hours. Blackbaud has been saying that they are improving it ever since they came out with NXT.
