> Key: MESOS-3161
> URL: https://issues.apache.org/jira/browse/MESOS-3161
> Project: Mesos
> Issue Type: Improvement
> Components: build, documentation
> Reporter: Benjamin Mahler
> Priority: Major
> Labels: newbie

> The [gold linker|https://en.wikipedia.org/wiki/Gold_(linker)] seems to
> provide a decent speedup (about ~20%) on a parallel build. From a quick test:
> {noformat: title=timings for make check -j24 GTEST_FILTER="" w/ 24
> hyperthreaded cores}
> gold:
> real 7m18.526s
> user 81m21.213s
> sys 5m17.224s
> default ld:
> real 9m7.908s
> user 85m13.466s
> sys 5m52.199s
> {noformat}
> On CentOS 5 w/ devtoolset-2:
> {noformat}
> sudo /usr/sbin/alternatives --altdir
> /opt/rh/devtoolset-2/root/etc/alternatives --admindir
> /opt/rh/devtoolset-2/root/var/lib/alternatives --set ld
> /opt/rh/devtoolset-2/root/usr/bin/ld.gold
> {noformat}
> On Ubuntu:
> {noformat}
> sudo update-alternatives --install /usr/bin/ld ld /usr/bin/gold 1
> {noformat}
> Ideally we could this out on the website, with instructions for each OS.
