[GitHub] [arrow-rs] Dandandan commented on issue #279: Performance improvements for take by specializing on 32 / 64 bit integer indices

   Some first experimenting didn't reveal a lot of options.
   What did improve performance however, was removing the bound check (-25%) but it doesn't seem like we can get rid of it without checking bounds for all values manual (which seems like it should be slower - even after speeding it up by 2x here https://github.com/apache/arrow-rs/pull/281 )
