[Building Sakai] Question pool slowness

[George Pipkin]

Hi -

   Thanks Karen and Will for your responses.  I took a look at
our tables current setup, and it looks like we not only got the
hibernate-created indexes, but the ones mentioned in
the sakai_samigo_post_schema_update.sql  script.  Could this be
causing us difficulties ?

                               - George
