--------------------------------------
Summary: Document using the gold linker for faster development on
linux.
Key: MESOS-3161
URL: https://issues.apache.org/jira/browse/MESOS-3161
Project: Mesos
Issue Type: Improvement
Components: build, documentation
Reporter: Benjamin Mahler
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 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}
Ideally we could this out on the website, with instructions for each OS.
