Application Performance Analyzer for z/OS, Version 11.1, User's Guide

Variances

A percentage value is displayed under the heading "Variance" in various segments of this report. Its value quantifies the variance between a particular performance figure for the compared measurement and the corresponding value for the base measurement. A plus (+) value indicates a higher value than the base measurement and a minus (-) value indicates a lower value. The value is the percentage by which the compared measurement figure exceeds (+) or is less than (-) the corresponding base measurement value. Any value exceeding 999 percent is reported as "999%." The magnitude of the value is also represented graphically by a string of greater-than or less-than symbols.
