Hi Bill,
If you can, please provide additional information so that folks here can help. Questions off the top of my head:
> I'm assuming your performance measurements are for reads and not writes?
> Assuming yes to above, what kind of queries are you running? BI/OLAP-type queries with aggregation and star-schema like structures? SELECT * FROM ...? Kitchen sink queries?
> How many tables are involved in your queries, what do the join conditions look like, where are calculations taking place (i.e. directly in the SQL itself), and what are the data volumes (in terms of record count)?
