If you don't use correctly this have a very bad performance.
you have to see the execution play to verify you are receiving through
the dblink only the information you need.
you have the driving site hint to help on that.
Now if this is too complex you can evaluate the positibility to create
a function table to return only what you need.
Previously on this list, this topic had been touched more deeply.

Is there an good reference to read about, when and when not to use db-links?
