I suggest you move the input of alert data into the database to Barnyard. (If you are not already doing so)
I would also periodically clean out the DB (clean out old stuff, and stuff you don't need.)
Finally, switch to BASE instead of ACID. http://base.secureideas.net Joel On Nov 1, 2005, at 11:17 AM, Hubert Edward kIYIMBA wrote:
