If your training database is very large then it could have an impact on
processor utilization.  Just how big is your training database?

It usually isn't necessary to train on every message you receive, and if
you've received 25,000 spams in about 3 months then I suspect your
training is heavily over-balanced toward spam anyway.  I would suggest
retraining on a much smaller set of messages (50-100 of each is probably
more than sufficient).  After that, be more selective about which
messages you actually train on.  If most of your messages classify
correctly then you shouldn't need to train much at all.
