Configuration

Windows build number:

  • Windows 7 SP1: Microsoft Windows [Version 6.1.7601]
  • Windows 10 1809: Microsoft Windows [Version 10.0.17763.253]

What you're doing and what's happening:

With Windows 7, executing build_gcc.bat (1000 x gcc-arm-none-eabi) in Command Prompt takes 0:46.
With Windows 10, the same script takes +78% longer time with default settings (01:22).

With Windows 7, executing build_cmd.bat (1000 x cmd.exe x 20) in Command Prompt takes 01:48.
With Windows 10, the same script takes +139% longer time with default settings (04:18).

Some observations:
With Windows 10, some computers show heavy (25-40%) GPU load when Command Prompt is scrolling.
A Windows 7 Virtual Machine running build_cmd.bat in Virtual Box on a Windows 10 host outperforms the Windows 10 host.

The strange thing is that starting Command Prompt with "Run as Administrator" on Windows 10 increases performance a lot - back to Windows 7 level. Using the "Legacy Console mode" checkbox only seems to have a minor effect.

See attached scripts and results.txt.

results.txt

What's wrong / what should be happening instead:

Windows 10 Command Prompt performance for build_cmd.bat and build_gcc.batshould be the same as with Windows 7, or at least the same as Windows 10 Command Prompt running as Administrator.

(The problem is that running a 10 minute build script might take 20+ minutes on Windows 10)
