How can I delete time spent in waiting and blocking functions?

A program can spend so much time in functions, procedures, or methods (collectively referred to here as functions) that wait on I/O, such as WriteFile or ReadFile, or that block on synchronization objects, such as WaitForSingleObject, that the data for those functions obscures the data for more critical functions.

To filter out these functions and their time, select View > Filter Manager or click images\filtermng.gif. In the Measurements tab, select Sys Wait and Sys Block and then click Delete, to delete the time from the current dataset.
