The MTT database is always in need of optimzation :-) What performance
results are you trying to search on?

In the MTT Reporter, there are some tricks to narrowing a search for
speedier results. E.g., if you wanted to compare a set of results from
last August and this week, a non-continguous date range could speed
things up by a lot. So instead of "past 6 months" as a date range, you
could do "2009-02-19 - 2009-02-25 | 2008-08-19 - 2008-08-25", which
would compare this week with six months ago (but it only searches on
the two boundary weeks, instead of the entire six months). To avoid
long searches on Test run data, clicking on the "MPI install" radio
button allows you to do a quick probe on whether you have *any* data
for a given date range. Then once you get a date range of where your
data exists, you can expand the search to include Test build and Test
run data.
