I've run into this lately, too.  I'm under the impression that the new 
2.0 text widget resolves many of these types of performance issues, does 
anyone know if that's correct?  In the meantime, you might try buffering 
your data and doing inserts at some periodic interval using a timer or 
an idle callback.
