Michael,
Thanks for your reply.
When is the next milestone expected?

definately upgrade to latest 3.0.x version (3.0.6).
Also, those methods are were most of the work happens, its a
common misconception that all the work happens lazily when you
call "fire all rules" but that is not the case, as you assert each
object, it propagates through the RETE network, so that is normal
to see the time spent there for lots of data.
you can also try the trunk version if you like, its certainly got
some improvements, but the next milestone (if you can wait) will
be more worth your time.

Hi,
I encountered a serious performance problem using Jboss Rules
3.0.1. The process was executed on a pretty strong machine - a
DL350 4 cpu RedHat machine. The process was using about 100%
CPU and I used a profiler to see what's going on:
My application adds/removes objects to/from the working memory
of a stateful rule session quite intensively (2000-3000 per
sec), though the intensive actions were related to a single
rule session and only a few extra rule sessions existed
simultaneously. It turned out that about 7-10% of CPU was
consumed per a single add/remove operation. More specifically,
ReteooWorkingMemory.doRetract() and
ReteooWorkingMemory.doAssertObject() were the major consumers.
I would expect a basic operation like this to be significantly
less CPU intensive.
Would you please provide more information, is my benchmark too
ambitious? Do you recommend an upgrade to version 3.0.6? 3.1?
If so, please elaborate what were the performance improvements.
Best regards,
Einat Idan
