Hi Nathan,<br><br>In you system, do all rules fire most of the time, or is it the type of system where only some of the rules fire each time you create a session? We&#39;ve recently introduced a feature that should improve performance, if it&#39;s the latter. You would need to get the latest snapshot for 5.2 from our repository and configure you rule base to activate it. It&#39;s described here: <a href="http://blog.athico.com/2011/05/left-right-unlinking-first-steps.html">http://blog.athico.com/2011/05/left-right-unlinking-first-steps.html</a><br>
<br>If you could provide some feedback, it would be very much appreciated.<br><br>Thanks,<br>Leonardo.<br><br><br><div class="gmail_quote">2011/5/23 Mark Proctor <span dir="ltr">&lt;<a href="mailto:mproctor@codehaus.org">mproctor@codehaus.org</a>&gt;</span><br>

        <p class="MsoNormal">I have a general question about the
          expected performance of 5.2. In a system with many facts and
          many rules what is the expected performance of 5.2 compared to
          5.1. In terms of speed is it expected to perform the same,
          better, or worse? And in terms of memory usage is it expected
          to be the same, better, or worse? I’m asking because I’m
          trying to decide how quickly to switch to 5.2 when it is
          officially released. If there are performance gains to be had
          I’ll want to move to it more quickly.</p>

    It should be better marginally better on performance and memory. The
    only exception to this is usage of &#39;from&#39;, which now attempts to
    preserve state changes on modifications, which is heavier<br>
