About 20 years ago I was evaluating solutions for reporting to see if we could save money switching from Crystal Reports. One reason we stayed with Crystal was they did something they other report engines did not; they made available for display every page as it was rendered. So for a 400 page report, you could start working with it immediately. It took each engine (with a couple exceptions) about the same time to generate the entire report, but for the other engines, you had to wait until they were done.

There is speed, then there is the perception of speed. Crystal got this right.
