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).<br><br>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"<br>

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

If you use a stateless session per transaction you should generally be OK.<br>
<br>
How much lag you're likely to encounter is a much harder question to<br>
answer: how well does your database retrieval scale, would this present an<br>
issue before the rules engine?<br>
<br>
The rules engine is "just a POJO library" the overall scalability would IMO<br>
depend upon your application's architecture.<br>

Hi,<br>
<br>
I have an Application where I have to give the discount to user according<br>
to their profile points.<br>
<br>
i.e. when the user logs in, his profile points are fetched from the<br>
database, and respectively he is given the required discount.<br>
<br>
My concern is how many concurrent users will be supported by the rules<br>
engine, will there a performance lag if the concurrent number of users<br>
exceed a certain limit. Please help me on this as I have no idea<br>
regarding<br>
this.<br>
<br>
Thanks and Reagrds,<br>
