[jira] [Created] (ARROW-17436) [C++] Use -O2, not -O3, for release/optimized builds

Antoine Pitrou created ARROW-17436:
--------------------------------------

             Summary: [C++] Use -O2, not -O3, for release/optimized builds
                 Key: ARROW-17436
                 URL: https://issues.apache.org/jira/browse/ARROW-17436
             Project: Apache Arrow
          Issue Type: Task
          Components: C++
            Reporter: Antoine Pitrou


-O3 can produce longer build times and larger binaries for next to no performance benefits.
We should perhaps tune down the optimization level to -O2 on non-MSVC compilers.
