[PERFORM] hyper slow after upgrade to 8.1.4

[Medora Schauer]

I have just upgraded from 7.3.4 to 8.1.4 and now *all* db access calls are extremely slow.  I didn’t need to preserve any old data so at this point all my tables are empty.  Just connecting to a db takes several seconds.   When I was accidentally linking my app with the 7.3.4 libs but running the 8.1.4 postmaster everything was fine.   I know I’m not giving much to go on but I’m stumped.  Can anyone suggest how I might track down the cause of this problem?   Medora Schauer
