(the progress bar may 'stick' at 100% for awhile.)ħ. Wait for the progress bar to finish and for the buttons to change from Save/Cancel to Open in WPA/Open Folder/OK. There's no need to type anything into the description area, but you can if you'd like.Ħ. [TODO: add illustrative screenshot or GIF or something)Ħ.and then click the Save button again on the next screen. I opened a 5 minute trace the other day while I was working on startup performance and it took 20GB of memory to load! Note that performance traces should usually be kept to about 1 or 2 minutes maximum because they can get really big, really fast. When sending the trace, make sure to include a description of what you're doing! Start Paint.NET and reproduce the performance problem. and wait for the button to change to saying "Save", which indicates it has initialized and is now "recording"Ĥ. Once that's completed, go to the Start menu and find Windows Performance Recorder ("WPR" from now on). You need to install the Windows Performance Toolkit. Do this by going to, click to download the "Windows ADK", and then within the installer choose to only install the Windows Performance Toolkit.Ģ. This is useful for when things are "slow" and we need to figure out what's causing it.ġ. Bruce Dawson's blog has a lot of cool posts where he shows himself using it to figure out all sorts of weird problems. It's very good for finding bottlenecks and figuring out what code is being problematic. I'll use something called Windows Performance Analyzer to load the trace and look at what code is executing across all of the threads and CPU's, file accesses, etc.
#Windows performance toolkit useful how to#
This post will give instructions on how to submit something called a "performance trace file", which will allow me to inspect pretty much everything going on during Paint.NET's execution at a very low level.
