In general, Corticon Studio includes many features that help rule authors write efficient rules. Because one of the biggest contributors to Decision Service (Ruleflow) performance is the number of rules (columns) in the component Rulesheets, reducing this number may improve performance. Using the Compression tool to reduce the number of columns in a Rulesheet has the effect of reducing the number of rules, even though the underlying logic is unaffected. In effect, you can create smaller, better performing Decision Services by compressing your Rulesheets prior to deployment. For more information, refer to the Rule Modeling Guide's chapter on Rule Analysis and Optimization.
