AntoinePrv opened a new issue, #48277: URL: https://github.com/apache/arrow/issues/48277
### Describe the enhancement requested The current algorithm `unpack` algorithm in the `bpacking` files do not fully leverage SIMD operations and perform poorly on SSE4.2 (in fact they are not built for that reason). They are also not available for multiple sizes. We can take inspiration from - http://arxiv.org/abs/1209.2137 - https://github.com/fast-pack/LittleIntPacker/blob/master/src/horizontalpacking32.c ### Component(s) C++, Parquet -- This is an automated message from the Apache Git Service.
