Re:OCaml Multicore merged upstream by gautamcgoel on Monday January 10, 2022 @10:34AM (#29876391)
Been reading about this work for years, really cool to see it get merged! I recently came across a neat interview which describes upcoming changes to the OCaml GC and memory management system, which apparently lead to huge performance gains:

The "huge performance gains" refers to the prefetching optimisation, which is already in OCaml (the old OCaml 4 branch, not in multicore yet).
