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"

Thanks Michael for the help. But, is there any benchmark or a rough figure
like number of hits or number of rule fired per minute, for normal
performance.

If you use a stateless session per transaction you should generally be OK.

How much lag you're likely to encounter is a much harder question to
answer: how well does your database retrieval scale, would this present an
issue before the rules engine?

The rules engine is "just a POJO library" the overall scalability would IMO
depend upon your application's architecture.

 Hi,

 I have an Application where I have to give the discount to user according
 to their profile points.

 i.e. when the user logs in, his profile points are fetched from the
 database, and respectively he is given the required discount.

 My concern is how many concurrent users will be supported by the rules
 engine, will there a performance lag if the concurrent number of users
 exceed a certain limit. Please help me on this as I have no idea
 regarding
 this.

 Thanks and Reagrds,
