@arnaud.giuliani please, do something about the performance soon or we'll be forced to abandon Koin. We cannot afford to have a slow app because dependency injection.
If you apply the fix using a hashmap instead of iterating through all the dependencies every time at least some users will have a performance boost ( still far from all other DI frameworks ).
But mostly the issue here to me is about feedback, if you just say: "I'm thinking if I should rewrite the core" we are terrified, because we don't know when or if it will happen at all, and in the meantime we have to go back to Dagger, or try another framework like Kodein ( and obviously once we move away, the possibilities that we try again Koin are very remote )
