It's hard to see why that's happening without more information. The only thing I could think of is the change related to

Found the reason of slow down. I have added bower package "material-design-icons": "~2.2.0" which is very huge 50MB and this caused performance issue. I haven't still found the way to resolve it because my bower and node packages are excluded in ts config and my task looks like this:

Thanks everyone! I think I have fixed the issue. The problem was that Can everyone check whether this has fixed the issue? You can download gulp-typescript here from GitHub and place it into your |

Compiling my project increases from 7s (2.10.0) to 17s (2.11.0). In both version I don't see real speed increase using
