[rules-users] Expected relative performance of 5.2

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. Thanks, Nathan Bell
