Till Toenshoff updated MESOS-4709:
----------------------------------
Shepherd: Till Toenshoff
> Enable compiler optimization by default
> ---------------------------------------
>
> Key: MESOS-4709
> URL: https://issues.apache.org/jira/browse/MESOS-4709
> Project: Mesos
> Issue Type: Improvement
> Components: general
> Reporter: Neil Conway
> Assignee: Neil Conway
> Labels: autoconf, configure, mesosphere
>
> At present, Mesos defaults to compiling with "-O0"; to enable compiler
> optimizations, the user needs to specify "--enable-optimize" when running
> {{configure}}.
> We should change the default for the following reasons:
> (1) The autoconf default for CFLAGS/CXXFLAGS is "-O2 -g". Anecdotally,
> I think most software packages compile with a reasonable level of
> optimizations enabled by default.
> (2) I think we should make the default configure flags appropriate for
> end-users (rather than Mesos developers): developers will be familiar
> enough with Mesos to tune the configure flags according to their own
> preferences.
> (3) The performance consequences of not enabling compiler
> optimizations can be pretty severe: 5x in a benchmark I just ran, and
> we've seen between 2x and 30x (!) performance differences for some
> real-world workloads.
