Performance Validator Help


Managing multiple sessions


Performance Validator can manage multiple sessions at once.


As well as the actively running session, open sessions may include those run since Performance Validator started, or reloaded sessions that had been saved earlier.


menu Managers menu instructionStep Session Manager... instructionStep shows the Session Chooser dialog below, highlighting the current session




Each time a session is started or loaded it is added to this list, using the name of the executable program and the date and time the session started.



Managing the sessions


Select instructionStep makes the selected entry the current session, i.e. the one for which data will be displayed


note Some tab views may update immediately, others may need a manual refresh


Set Alias... instructionStep opens the Edit Session Alias dialog so you can give the session a more useful name



Delete instructionStep removes the selected session


You can't delete a session that is actively collecting data.


Delete All instructionStep removes all the loaded sessions


If one of the session is actively collecting data, this will be disabled.


Close instructionStep closes the dialog (as opposed to closing any selected sessions!)



Comparing loaded sessions


When two different sessions are loaded they can be compared as part of a manual regression test.


The comparison results are shown as a call tree, detailing the difference in timings at each node.


Compare... instructionStep shows the Compare Session dialog for comparing hotspots.





Limiting the number of sessions


You can choose to limit the maximum number of sessions open at once.


Once this limit is reached, then each time a new session is added, the oldest session may automatically be removed:


Auto purge sessions instructionStep ensures that the number of loaded sessions is limited to the maximum (below)


Maximum number of sessions instructionStep sets the maximum number of sessions allowed if auto-purge is on
