[rules-users] Expected relative performance of 5.2

[Leonardo Gomes]

Hi Nathan,

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've recently introduced a feature that should improve performance, if it'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's described here:

If you could provide some feedback, it would be very much appreciated.

Thanks,
Leonardo.
