             Summary: Stout's UUID re-seeds a new random generator during each 
call to UUID::random.
                 Key: MESOS-3046
                 URL: https://issues.apache.org/jira/browse/MESOS-3046
             Project: Mesos
          Issue Type: Bug
          Components: stout
            Reporter: Benjamin Mahler


Per [~StephanErb] and [~kevints]'s observations on MESOS-2940, stout's UUID 
abstraction is re-seeding the random generator during each call to 
{{UUID::random()}}, which is really expensive.

This is confirmed in the perf graph from MESOS-2940.
