Why would you want to setup Bayes on a per user basis if you are going to feeed it system-wide hams and spams? Especially feeding it systemwide hams is odd. >> A weekly collection run for 1 user usually eats 100% of CPU load.

Systems shouldn't crash under high load, so that's not a real concern. If it does happen, you have a more serious problems elswhere. What would be more of a concern is how it is going to affect other processes running on your system. Slower is not a problem, but if you really put the load on your box from a lot of processes, you might start seeing time-outs. >> All hints will be appreciated, for we scheduled an initial load for >> 16 users of the big collection of spam received so far. If your are going to simultaniously learn spam and ham for 16 users, and want to keep running your mailserver/spamassassin too (it take you also have a virusscanner running somewhere), I would consider at least running the sa-learn processes under nice to keep them from stalling more essential services. But, depending on your System setup (OS, DB, etc) you might want to cut down a little on the number of processes run simultaniously. >> >> Thanks guys >> >> Chavdar Videff >> >> > What kind of Bayes db are you using?
