[rules-users] large rulebase load time

[Edson Tirelli]

   Joe,

   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?
