Look at the OSDL test suite, and run as much (or as little) of it as you
can against both databases.  it's a rather large and complex couple of
suites.

Test under heavy parallel use.

Test returning large data sets from complex queries, esp OLAP type
queries that do a lot of work in one query to mine data in certain ways.

Tune both reasonably according the the best practices for each database.
