I have been wondering why testing on my Windows 8.1 machine takes forever, turns out Avast’s DeepScreen tries to analyze every go binary and therefore slows the entire process down by a factor of more than 10 if not 100.
Since I could never find an answer on the internet why it took so long, I’m writing this down for future generations of Gophers.
@matt I second your recommendation. I dropped Avast for Windows Defender that comes with Windows 8 after the previous issues I had. @trichner if you continue to use Avast and find you can’t load some webpages you might want to look at disabling HTTPS scanning in the Web Shield.
