Question #1
A company is running 20,000 rules in one ruleset and experiences latency during some ruleset executions. No hot deployments are used.

What should the application developer do to minimize the impact of ruleset parsing and speed up performance?

A. In the ra.xml file, set the pool.maxSize parameter to make sure that the number of active rulesets is greater than the size of the XU connection pool.
B. In the ra.xml file, set the asynchronousRulesetParsing property to false to handle concurrent requests.
C. Set the ruleset property ruleset.maxIdleTime to 0 to ensure the ruleset is not removed from cache.
