--------------------------------------

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.
