If you spend 99% of your time coding and 1% of your time compiling, does it really matter that much?
the resharper plugin to visual Studio or the rider ide will both do this. Only builds the projects required and doesn’t need to build dependent projects unless a signature changed.
It's not comparable whatsoever to how much faster Java is. In Eclipse it basically compiles in the background right after saving a file so you never feel the impact of compilation.
I'm not sure now, but 10 years ago I was really feeling the impact of compilation in eclipse.
On a big project that I was working on it was taking about 20 minutes for a full build and I had to disable the background compilation because it always messed up stuff and my code would be out of synch.
I think that in general Java compilation feels a bit faster, but for sure you can't say that you don't feel it at all in big projects.
