Visual Studio 2015 is very slow


I just finished the installation and the whole IDE is super slow. It seems like it's making some kind of heavy CPU calls in the background where the whole IDE literally freezes and becomes unresponsive for about 2-3 seconds.

I was not having this issue with Visual Studio 2013 Ultimate. I am running Visual Studio 2015 Professional.

Installed Add-Ons/Packages:

  • Node.js Tools
  • ReSharper

Anyone have any ideas?

I found that the Windows Defender Antimalware is causing huge delays. Go to Update & Security -> Settings -> Windows Defender. Open the Defender and in the Settings selection, choose Exclusions and add the "devenv.exe' process. It worked for me
