[jira] [Created] (ARROW-17305) [C++] BitmapAnd benchmarks are popcount-limited

Antoine Pitrou created ARROW-17305:
--------------------------------------

             Summary: [C++] BitmapAnd benchmarks are popcount-limited
                 Key: ARROW-17305
                 URL: https://issues.apache.org/jira/browse/ARROW-17305
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Benchmarking, C++
            Reporter: Antoine Pitrou
            Assignee: Antoine Pitrou


The {{BitmapAnd}} benchmarks in {{bit_util_benchmark.cc}} spend much of their time computing a popcount after running the actual operation (for the sake of ensuring the compiler didn't optimize it out).
