Re: [PATCH] gitlab-ci: Build MSYS2 job using multiple CPUs

[Thomas Huth <thuth@redhat.com>]

According to 
https://docs.gitlab.com/ee/ci/runners/hosted_runners/windows.html the 
Windows shared runner should have 2 vCPUs nowadays, indeed! Maybe worth to 
mention it in the patch description?

Also, how much faster does the job now run for you?

Well, we're calling into bash there, so you could do it as part of the bash 
statement?
