Just to add that recent improvements in IBO default management (Gb? Gc?) makes the default values of all the database being automatically retrieved only once from the server and stored in memory in the schemacache (this is automatically done with the GetServerDefaults set and when any datasets is going to insert mode).
So even if you don't use a "local copy" the performance issue is very little (of couse, if you use a modem connection it counts, but with lan it's really little).
