Grant Henke updated KUDU-830:
-----------------------------
Target Version/s: (was: 1.5.0)
> Ensure thirdparty builds with fastest compiler for releases
> -----------------------------------------------------------
>
> Key: KUDU-830
> URL: https://issues.apache.org/jira/browse/KUDU-830
> Project: Kudu
> Issue Type: Improvement
> Components: build, perf
> Affects Versions: Public beta
> Reporter: Todd Lipcon
> Priority: Major
>
> On el6 slaves, it appears we currently build all of thirdparty with clang 3.3
> from toolchain. This is a pretty old compiler which generates slower code
> than gcc or newer clangs. It's not a big deal for most stuff, but probably
> measurable difference on compression codecs like zlib/lz4. We should make
> sure we use the best compiler for these perf hotspots.
