It's unclear if it will speed up reports per se, but yes, we've
certainly talked about this.  It's something that's more interesting
once we get a standard SQL backend.  With the current XML-File backend
you have to load the whole data file anyways, whereas with SQL we
might be able to load only a partial set of data with baseline
summaries,
