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

             Summary: Hierarchical allocator performance is slow due to Quota
                 Key: MESOS-4505
                 URL: https://issues.apache.org/jira/browse/MESOS-4505
             Project: Mesos
          Issue Type: Improvement
          Components: allocation
            Reporter: Joris Van Remoortere
            Assignee: Joris Van Remoortere
            Priority: Blocker


Since we do not strip the non-scalar resources during the resource arithmetic for quota, the performance can degrade significantly, as currently resource arithmetic is expensive.

One approach to resolving this is to filter the resources we use to perform this arithmetic to only use scalars. This is valid as quota can currently only be set for scalar resource types.
