Why scala compiler slow. and hydrate 3.2 x faster than scala compiler?

Is there any core team look at compiler compile speed?

for now , the most power and speed compiler i seen. It is golang and ziglang.

very fast and impressive.

Thanks for creating this @cnmade. Note that Hydra actually doesn't work with Scala 3 and is only focused on Scala 2. Regarding performance, there is definitely a focus on improving the speed, but there isn't a dedicated team for this. Feel free to check out the performance issues in Dotty for some ideas.
