Yes. > Does multiple instances of Rete means multiple sets of Rule engines? Yes. Each Rete object is a completely separate rule engine.

You can duplicate them, but not share them. > Does JESS is good on high volume loading means say 10000 calls per > second or so? Jess's performance depends on many factors; this is somewhat like asking whether you can make 10000 Java method calls per second. Sure you can, if they're empty. No, you can't, if each call copies a 100GB file over a modem link. Similarly, on a modest machine, Jess can fire hundreds of thousands of rules per second, if the rules don't do much of anything. Your own results will depend on the Jess programs that you write. > In order to learn, does JESS has to be running always? Don't know what you mean by "learn" -- Jess implements no learning algorithm. --------------------------------------------------------- Ernest Friedman-Hill Science and Engineering PSEs Phone: (925) 294-2154 Sandia National Labs FAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)
