This is huge. I'm seeing a 3.6x improvement on M1 Pro 🙌

Such a shame this library is not being maintained anymore

Hi @Kinbaum, your fix is available in radashi@beta today (see #13). An official release is pending. We'd love to have you participate in the discussion and/or development of the radashi-org/radashi fork. 😄

@rd-xx You are invited as well!

Hi @aleclarson, thank you very much for your work. I had no idea radash had an active fork, I will be making the switch soon enough :)
