[rules-users] Drools Performance

[Michael Anstis]

Not that I'm aware of (although the general "performance" topic comes up on
this forum from time-to-time, so other users may report back).

Obviously performance of rules depends on how complex they are; and whether
you then optimise them - much like "how many SQL queries can RDBMS xyz
execute per second"
