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.
This report segment compares the TCB CPU times that were recorded by the operating system during the measurement sessions.
This report segment compares the SRB CPU times that were recorded by the operating system during the measurement sessions.
This report segment compares the number of EXCPs that were processed during the measurement sessions.
This report segment compares the number of service units recorded by the operating system during the measurement sessions.
This report segment compares the percentage of samples during which one or more TCBs was executing CPU instructions.
This report segment compares the percentage of samples during which all TCBs were in WAIT state.
This report segment compares the percentage of samples during which no CPU activity was taking place but one or more TCBs was suspended and waiting to be dispatched.
