It was pretty interesting to see Floki get a lot faster and Meeseeks actually get a little slower with OTP 21. I'll enjoy figuring out why. I hope to get a chance to work on the OTP 21 performance of Meeseeks before too long. On the plus side there were some nice memory improvements for Meeseeks in OTP 21. |

Don't let this sound patronizing because it's not -- but have you looked at how many times is the boundary between the BEAM and the Rust code crossed? I haven't inspected Meeseks' code so can't talk, just wildly guessing.
My ancient experience with Java <-> C++ bridges has taught me that if your higher-level language calls the lower-level language very often then the gains of using the lower-level language almost disappear due to the high overhead of constantly serializing data back and forth.
Anyhow, we should probably take this discussion to ElixirForum and not here. :)
