it is interesting how reluctant you are to use a real dbms

are already taking advantage of the dbms and the fact we (SDSS)

did the job of creating a galaxy table for you.
If you want to do the real test you should go to the DAS and start
collecting the cvs files
This isn't the point. It is not clear that RDBMS map well to
the tasks that astronomers want to do. For example, you wouldn't load
the raw pixels into SQL-Server and start flat-fielding and detecting
objects.
Root is a system designed to enable scientists to write code, and it
might
well have done Much better than SQL-server. If it had beaten out the
RDBMS
by a factor of 100 with a fair hardware comparison we would have to
look very
closely at our assumptions of what we wanted our DBs for.
As a matter of fact, the RDBMS did (surprisingly?) well.
