[rules-users] Package footprint

[JP Chemali]

Hi all,

I'm trying to reduce the memory footprint of packages in my application (for
performance reasons they are dynamically loaded from disk), and I was
wondering if some of you had any experience with the subject?

So far the optimizations that I can come up with in 5.4.0.Final version are
all about reducing the sizes of generated classes:
- Package name in the drl file should be as small as possible, one letter is
best (even better that no package at all)
- Rule name should be as small as possible as it is used to generate the
consequence class name
- Write as less code as possible in the consequence
- Use as few as possible eval statements
- By using my own JavaDialectConfiguration and MVELDialectConfiguration when
building the knowledge, I can remove the random number on class names that
was added in the recent versions (don't understand why it was added in the
first place? Does anyone know?)

I see some leeway to shorten the names of the following generated classes
but the amount of overriding to change the "default" consequence name and
the suffixes is a bit too exotic for me:
- <PackageName>.<RuleName>DefaultConsequenceInvoker
- <PackageName>.<RuleName>DefaultConsequenceInvokerGenerated

Any advice, other leads some of you might have?

Thanks in advance
