[jira] [Created] (ARROW-4670) [Rust] compute::sum performance issue

Andy Grove created ARROW-4670:
---------------------------------

             Summary: [Rust] compute::sum performance issue
                 Key: ARROW-4670
                 URL: https://issues.apache.org/jira/browse/ARROW-4670
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust
    Affects Versions: 0.12.0
            Reporter: Andy Grove
            Assignee: Andy Grove
             Fix For: 0.13.0


I'm running some microbenchmarks over at [https://github.com/andygrove/row-vs-col-rs] to compare performance of arrow to just using Vec<> and I'm finding that Arrow is 18x slower in these benchmarks.

I am quite surprised at this performance difference so am creating this issue and will attempt to optimize the code.
