Do you know if they attempted to tune MUSH'es basic data model to fit
the new storage behaviours, or if they just attempted to supplant the
basic dbm with an SQL structure?  The numbers you report would seem to
suggest a straight transplant without attempting to tune the data
model for the new medium (while I can't comment on the SQL world, a
few custom indexes or localised cacheing would handle the local object
list provlems poste haste in the DB2/Progress worlds I used to play
in).
