Wow, that is a lot of data. Do you want to make a sale or just speed things up for them? If you move them to subscription, don't they get to move at NC? Can they purge some of their data? that would speed things up. If only a few reports are slow, consider Pass Through Queries via and Access database. I have had some clients run the SAME Crystal report 10X faster simply by using Access. Did you write the Crystal reports for them? @ThereseLogeais has rewritten some for me that are now screaming fast for the client. DSD has a SQL mirror product that might work for them.
