@pitrou here are some benchmarks in the [0, 500] num of integer to unpack that Arrow is operating over. - SVE128: [linux-arm64-graviton4.pdf](https://github.com/user-attachments/files/27016293/linux-arm64-graviton4.pdf) - SVE256: [linux-arm64-graviton3.pdf](https://github.com/user-attachments/files/27016255/linux-arm64-graviton3.pdf) As before, we can sometimes be much penalized by small sizes. Surprisingly (annoyingly?) there are some bit width numbers (e.g. 3, 5, 6, 7 on SVE256) where the world is upside down: scalar does best, then Neon, then SVE (in the [0, 500] range, it does not hold for larger input buffers). -- This is an automated message from the Apache Git Service.
