----------------------------------

             Summary: High CPU usage of mesos-slave when running many tasks
                 Key: MESOS-2251
                 URL: https://issues.apache.org/jira/browse/MESOS-2251
             Project: Mesos
          Issue Type: Bug
          Components: slave
    Affects Versions: 0.22.0
            Reporter: Dario Rexin


Starting many tasks (in my case 80) on a single slave leads to extremely high cpu usage of the slave process. On a 4 core (4GHz Core i7 8 Threads) I observed up to 210% CPU usage. The CPU usage only goes down, when the tasks are stoppped.
