True. I don't have a better answer for your original question on a slowdown. There may be some db tweaks to do. Shrinking your database would most likely shrink the update times too. Btw, automatically rebuilding a bayes db from scratch (once it has grown way too large) is not too bad, provided the autolearning is given quality data to work on. Letting SpamAssassin check outgoing mail is one component of this: gives it an opportunity to see and learn mostly ham. Letting SpamAssassin see all incoming mail (no graylisting and limited RBL checks at the MTA level) gives it an opportunity to get a good overview of typical spam. Coupling such good sources of ham and spam with a quality set of network tests and rules usually results in building a good initial Bayes database quickly with no manual intervention. After the initial autolearning the MTA-level spam controls may be turned back on again. Mark
