Subject: Performance Tuning
To: Rules Users List <rules-users(a)lists.jboss.org>
I am trying to improve performance on a Large DataSet, few Rules app
and came accross these two properties, which by default is false:
RuleBaseConfiguration.PROPERTY_INDEX_LEFT_BETA_MEMORY
RuleBaseConfiguration.PROPERTY_HASH_ALPHA_NODES
What do they mean actually? How and when should I use them?
I am trying to chase a O(n^2) performance problem that I understand it
is probably caused by the way I coded the rules, but it seems that I
need to deepen my understanding to actually find the hotspots. Are
there any techniques (that I probably dont know) that can help me find
what rule(s) is causing the issue?
As always thanks for previous answers
