Deferring Data Analysis to Increase Accuracy for a Trace Document

Increase the accuracy of performance-related data by deferring data analysis until you quit the application you are testing.

To defer data analysis in order to increase accuracy for a trace document
  1. Choose File > Record Options.

  2. Select the Deferred Mode checkbox, then click OK.


In its default mode, Instruments analyzes and displays data while your application runs—allowing you to view the data as it is collected. Deferred mode delays the analysis of data until the data collection is done, either after your application has finished running or after you click Stop. During data collection you are blocked from interacting with the instruments that are collecting data.

In deferred mode, after Instruments has finished collecting data, Instruments processes the data and displays it on the screen. Deferring the data analysis adds time to the back end of the data collection process, but it helps ensure that performance-related data is accurate.
