| 2025-08-13 20:01:46 | <sixteenrats> | Hi, I'm sure this question is asked a lot, but is Haskell ever faster than well optimized C, especially in very parallel code? I.E. does it ever make sense for me to rewrite a very performance critical section of parallel C code in Haskell, or is it more worth my time to try to optimize the C? The specific project this would be for is for mid-at-coding/cablegen, and probably would be most of the |

| 2025-08-13 20:03:30 | <sixteenrats> | The reason I'm asking is because a very similar project to mine uses somewhat similar constructs to Haskell's paralellism and outperforms my C by a fair bit. |

| 2025-08-13 20:22:47 | <geekosaur> | there's at least one known case where haskell came in noticeably faster than C. but parallelism will depend a lot on how it's done (neither language auto-parallelizes, and except in simple cases that's still a very open topic of research) |
