The only data that should be required to build the experiment pages is the
phenodata data frame and the experiment meta data.  

In an email conversation, Jeff suggested that the slowness is due to building a
geneid cache.  

Is that really what is going on?  If so, why?

If not, we need to at least understand why this is slow.  I would expect that
pulling this much data from the DB would not be so slow, but certainly I could
be wrong about that.
