Hello,We have recently moved a database to Amazon EC2 instance. We chose the server with identical configurations. The performance on the new server is awful. After initial analysis I realized that the old one used much more memory through AWE enable option, and so I reset memory on the new server the same way. However, it does not seem to have helped the problem.The only idea I have is to rebuild indexes. The only problem is that db size is pretty big (~ 80 GB) so it might take a while. So before doing that I wanted to get some opinions as to whether I am on the right track or there is something else to check.Thank you!
