Performance

The EmailPlus package uses caching techniques to avoid continually retrieving information from the ClearQuest® database. Caching minimizes the impact of evaluation and execution of the email rules on the IBM® Rational® ClearQuest environment. Because the email rules provide significant flexibility, construct the rules to ensure that advanced rules minimize their own impact on performance. EmailPlus caches in memory all rules for any given record type the first time they are examined in any ClearQuest session. Regardless of the number of rules a single record type has, only one record is fetched from the database. The Simple EmailPlus rule phrases are not evaluated by using ClearQuest queries. Simple EmailPlus rule phrases are evaluated entirely in memory.
