The DSL system is enabled in MR2, it should be mostly backwards
compatible and has a number of improvements - but be aware of the
existing upgrade versions, like the no boxing of primitives. Give it a
try and let us know how it goes.<br>

<pre wrap="">Mark,
I did see the MR2 release in your site. we need to use dsl.
Is there any change in this release as far as dsl is concerned.
we already used version3.0.6 and created all dsl.
can we use the rules as it is in the new release especially DSL?
Please let me know.
Thanks and Regs,
Basha

M3, so it won't be in this upcoming release, but the one after. there
will be partial DSL support in M2, at the engine level, but not at the
IDE level.

I did see your reply on one of the question that DSL is not enable for
M1. In which version it will be enable. we plan to use milestone.
Is it going to be enable or DSL feature going to be removed?
Thanks and Regs,

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

Hi Mark,
Thanks, these is good news!
My product is planned to be GA in 4-5 months. When do you recommend shifting
from 3.0.1 (that's the version I currently use) to 3.1? When do you expect
3.1 to be a stable version?
Best regards,
Einat
