hi, I tried using k2 with my project, and I experienced extremely log build times for it I don't have any concrete benchmarks to compare, but it took the compilations from like 10-20 seconds to upwards of a few minutes, which was a massive regression (though perhaps that's only because it previously had everything cached? unsure.) I'm going to profile/measure it later, so I can give more concrete measurements for it. my project is a multiplatform library, though it is currently only comprised of common code, no platform-dependent code, but k2 should be built with that in mind, no?

I have the opposite experience. K2 compilation is almost twice as fast (js and wasmJs targets with most of the code in the common module, Kotlin 1.9.20-Beta2).

I believe that the longest compilation was due to compiling the jvm code, but I could be mis-remembering
