Mojo is on the list and performed well. Have a look

its 2x slower than C in matmul which is something I wouldn't expect mojo to be slow at

2x slower than C while not optimal at all is not something I would call 'Slow' in this context. Still pretty strong considering how much more friendly it is to write code on for the average user of the languages in the context discussed here

IMO it looks way too verbose compared to the (faster) Julia implementation in this repo.
