    Description

      Qt Creator 11.0.2, Windows 10, AMD Ryzen 9 3950X 16-Core Processor, 64 GB ram.

      Tried the following:

      C:\Qt\Tools\QtCreator\bin
      $ set QT_MESSAGE_PATTERN=[%{time process}] [%{appname}] %{message}
      
      C:\Qt\Tools\QtCreator\bin
      $ qtcreator -profile
      
      C:\Qt\Tools\QtCreator\bin
      $ qtcreator -profile
      
      C:\Qt\Tools\QtCreator\bin
      $ qtcreator -profile
      
      C:\Qt\Tools\QtCreator\bin
      $ qtcreator -profile -noload QbsProjectManager
      
      C:\Qt\Tools\QtCreator\bin
      $ qtcreator -profile -noload QbsProjectManager
      
      C:\Qt\Tools\QtCreator\bin
      $ qtcreator -profile -noload QbsProjectManager 

      Captured the output with DebugView and saved it as qtcreator-11.log

      C:\Users\Cristian\Desktop

      Notice that the average startup time went from 8.94s to 4.9s. That's quite some difference.

      I've attached a screenshot of the installed Kits:

      Below is also my Visual Studio setup:
