Re: [rules-users] Expected relative performance of 5.2
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.

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.
It should be better marginally better on performance and memory. The only
exception to this is usage of 'from', which now attempts to preserve state
changes on modifications, which is heavier
