VS 2017 - Very slow (laggy) when debugging

Question

When I debug my solution, vs 2017 is very laggy and slow it\'s like it has to operate something heavy in the background.

So it stops \"responding\" every 5 seconds for 2

Answer 1

After some additional investigation I found this thread Unchecking Enable Diagnostic Tools while debugging in Tools → Options → Debugging → General did the trick!

Unchecking Enable JavaScript debugging for ASP.NET in
Tools → Options → Debugging → General
makes a huge difference in performance.
