[rules-users] What's more efficient too ?

[Edson Tirelli]

   Same answer: most of the time, it is better to have it as a fact, but
sometimes, a from may be better by limiting your search space.

   Again, these things are like SQL. You need to look at the whole domain
model as well as the set of your rules. The major performance optimizations
are made on a rule-set level, not individual rules. So, if you want the best
performance you need to write your individual rules to work better as a set
of rules, sharing nodes, reducing partial matches, etc.
