reports - excruciatingly slow

Yes, the reports were modified between 1.8 -> 2.0 and the algorithms
in use are much slower than on previous versions.

Yeah, compression wont make a difference.  The main issue is the number
of transactions.  The time to run the report is based only on that
(and, of course, the speed of your computer and how much RAM you have).

It would be nice to re-work the reports (again) to fix the algorithms
so they aren't O(n^3) (or whatever it is).
