What is the performance cost of software tracing
https://docs.microsoft.com/en-us/windows-hardware/drivers/devtest/what-is-the-performance-cost-of-software-tracing-
In general, the performance cost of software tracing is very small. The code is minimized, the buffers are managed efficiently, and the messages are written in binary format. Also, formatting trace messages, which is a big performance drain, is deferred until the user chooses to format and display the trace messages.

The Windows trace PreProcessor (WPP) provides high-performance tracing for C++ apps. It has low impact on binary size and CPU usage -- even when tracing is turned on -- which makes it suitable for both Debug and Release builds. It is however difficult to set up, especially in Universal Windows/Windows Phone Store apps.

Hi, Is there a way to analyze an *.etl file that I've generated using WPP macros (in a user mode app) using other tools than those from driver toolkit (e.g. tracewpp tracefmt). The problem with performance analyzer (from perf toolkit) is that it does not decode them and shows classic provider ... · Try using the Message Analyzer (follow-on to the ...
