+Atm GN2 is un-usable for Rob for basic tours and show-and-tells, and
+it is a persistent problem that is getting worse the more he
+complains.  Correlation is slower than it was ever before; and search
+is broken. For a simple search of 10,000 phenotypes, it takes a lot of
+time to compute.
+
+According to Rob, GN1 does not rely on a cache. Instead it is
+computing from a materialized view of the database that is
+intentionally designed for a fast web service.
