The Full, Init, and Delta links of the Performance report (PAL) provide detailed data about a single row of the display. The scope of information on this window depends on which link you clicked on the Performance report:
Hold the mouse pointer over a statistic to view ToolTip text.
The number of decimal places in timing results depends on the hardware and software supporting PRPC. In general, the decimal places reported are significant. Per-requestor CPU statistics are not available for UNIX platforms. R-14873 The value NaN indicates a divide-by-zero or other numeric exception.
All performance statistics are property values on a clipboard page of the Code-Pega-PAL class.
The header area at the top of the display contains these statistics.

Statistics in this area report how many times rules of various categories were executed for this requestor. Only rules of rule types subject to rules assembly — that is, rules converted to Java — are counted.
Counts increment when an operation starts, not when it ends.
These statistics are summarized across all requestor sessions in the shutdown report. See Working with the shutdown Rule Usage facility.

Storage Stream values — values of columns named pzPVStream — have one of three formats (V4, V5, and V6). A setting in the prconfig.xml file or Dynamic system Settings determines which format the system uses when it saves a Storage Stream. Your system may contain a mixture of formats, even in a single table, because the setting takes effect on a row-by-row basis.
For example, if you open an instance (a row) containing a Storage Stream in V4 format, update the instance, and save the instance, the system saves Storage Stream in the current format, typically V6.
The Instances Read counts do not include Storage Stream instances read from the rule cache.

The system captures performance details for interactive users at the interaction level, but this data is not retained.
The system also captures performance details for each requestor once each hour and also at sign-off. The usage daemon saves these details as instances of the Log-Usage class. You can report on these details using SQL reporting tools and the pr_perf_stats database table. See How to analyze system-wide usage with the Log Usage class.
