It is slower than LZ4 on AArch64.

  Source?

    Just tested a few minutes ago on the ClickBench dataset. Overall quite good, but, depending on particular columns, most of the time slower - e.g., ~2.0 vs ~2.8 GB/sec on Graviton 4 machine in AWS.

      You probably meant MB/sec not GB.

        No? Decompression is rated in GB/s per core now.

          Parent fixed the error I pointed out since making my post by dividing by a thousand instead of changing the units so now my comment looks wrong. It used to say 2800 GB/s which is obviously bonkers.

            Yes, it was a typo. Thank you!

  Could you tell me what your test setup and corpus was? For reference, to test ARM64, I tested v0.1.0 on an M3 mac with this fork of lzbench: https://github.com/welcome-to-the-sunny-side/lzbench/tree/add-misa77 https://github.com/welcome-to-the-sunny-side/lzbench/tree/ad... Here, lz4's decompression speed was far slower than misa77 and zxc. Results are here: https://github.com/welcome-to-the-sunny-side/misa77/blob/main/misc/lzbench-results-archive/0.1.0/apple-m3.txt https://github.com/welcome-to-the-sunny-side/misa77/blob/mai...
