I wonder if anyone tested if an identical application in kotlin would compiler faster given the new compiler?

It would be another good selling point to introduce it in the company.

I dont have a huge codebase that i can experiment on but i suppose kotlin devs did some benchmarks? how does it compare? does mixed codebase introduce significant overhead?

(In my experience, compile time isn’t really significant these days. My impression is that incremental builds are pretty quick, and full builds spent far more time checking/downloading dependencies, indexing, running tests, packaging, etc. than they do actually compiling. — Of course, it’ll depend very much on the project type and size.)
