Yes we have around 15-20K rules & each rule have different set of conditions
ANDed/ORed.
Some rules are small have 10-15 conditions but some have more than 100
conditions to be fullfilled to trigger the rule.
The eval() function was taking time & never loads the single rule.
So today I change my logic & start using java beans, & insert the patient
profile/data in CDEntryCache bean this will not fullfilled all of us
condition, as we have some complex matching condition need to communicate
with db e.g drug formualrtions etc but to give a try, I create the rule as
follows:
Following rule having some conditions which should be matched with
WM(patient profile) to trigger the alert.

end
The above rule have 36 conditions of CDEntryCache 3-4 conditions ORed with
each other then ANDed with another similar type of condition block. And it
takes so much memory of the system on kbase.addKnowledgePackages
the rule file is around 6kb but the knowdge package taking so much memory.
from 40Mb it goes to 401Mb
after kbuilder.getKnowledgePackages()
