I would like to have a zoom where I can make parts of the graph readable again. Zooming with Ctrl and the mouse wheel only zooms into the time region which is for a flame graph perhaps not what I want. The current flame graphs cannot really flame call stacks because the resulting flames become so small you have no chance to select them. You can stack two Wait views over each other so you can drill down to the relevant time where something is hanging and you can get to conclusions much faster now.Īnother nice feature is that if you select a region in the graph and hold down the Ctrl key you can select multiple regions at one time and highlight them which is useful if you frequently need to zoom in into different regions and you move between them. why your threads are blocking you get in the context switch view now a nice view what are the blocking reasons and which thread did unblock your threads most often. I have written some small tool to generate them also some time ago Visualize Your Callstacks Via Flame Graphs but it never got much traction. But a really new feature are Flame Graphs which Bruce Dawson wanted since a long time built into WPA. That makes hang analysis a whole lot easier.
#Windows performance toolkit useful update#
That feature is actually already part of the Windows 10 Update 1 WPA (6.15, th2_release.151119-1817) but I have come just over that feature now. Here is sample snippet of common sources of waits. Now you can assign tags for wait call stacks which is a big help if you want to have tags why your application is waiting for something. Not sure if the version number of the beta will change but it seems to target 6.1000. If you want to search for the changes here are the most significant ones. With the release of the first Windows Anniversary SDK Beta also a new version of Windows Performance Toolkit was shipped.
