Hi!
What about facts (I assume you don't just "play" with rules)? Do you retract LHS facts after using them, or do you keep them?
After restarting there are zero facts (a (reset) asserts the (initial-fact)) asserted in the engine. Depending on how many facts where previously stored in the engine, this can account for a very big difference. I once performed some tests where 10.000 facts, which were accidentally not retracted during the whole process, required some 10 MB of main memory.
Greetings

An: Jess Users List <[EMAIL PROTECTED]> Kopie: Thema: JESS: Memory utilization question |
In using version 50a6 (we're just now upgrading to 50b2) we find the
following:
We have the engine running as a long-running process.
We add, modify and delete rules incrementally over time.
As we do so, the memory grows.
Past a certain point, we save out the rules, shutdown and restart the
engine, and reload
the rule set previously saved.
Memory usage is significantly reduced after restart given the same set of
rules.
What accounts for the difference?
