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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
