<p class=MsoNormal> To be honest, I don't know. My guess is it
would be a bit faster as the consequence would be compiled only once, but I
have no numbers to compare... question: are you using a single builder and
adding multiple files/rules to it, or are you using one builder per file? Is
your application spending most of the time on the builder or adding rules to
the kbase? I see you are still using the old API (method
addPackageFromDRL())... does the new API make any difference? Also, I know
Tihomir was improving perf in trunk by caching the configuration file... did
you tried trunk? Does it make difference for you?<o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>For
a large rulebase (200k+ rules) will the call to addPackageFromDrl(drlString)
run faster if the number of rules is smaller but the rules include more ||
statements between predicates? <o:p></o:p></p>

<p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>There
is only one type of object ever inserted in working memory and I have many
