[jira] [Created] (MESOS-7521) Major performance regression in drf sorter

Dario Rexin created MESOS-7521:
----------------------------------

             Summary: Major performance regression in drf sorter
                 Key: MESOS-7521
                 URL: https://issues.apache.org/jira/browse/MESOS-7521
             Project: Mesos
          Issue Type: Bug
          Components: allocation
    Affects Versions: 1.3.0
            Reporter: Dario Rexin


The addition of hierarchical roles to the framework sorter (https://github.com/apache/mesos/commit/e5ef1992b2b8e84b5d1487f1578f18f2291cd082) has introduced a major performance regression to 1.2. Suppressing offers for frameworks does not seem to reduce allocation time anymore, like it used to in 1.2. Here are some relevant benchmark results:

Mesos 1.2:

[ RUN      ] SlaveAndFrameworkCount/HierarchicalAllocator_BENCHMARK_Test.SuppressOffers/7
Using 1000 agents and 6000 frameworks
Added 6000 frameworks in 105957us
Added 1000 agents in 34.937438secs
allocate() took 27.408828secs to make 1000 offers with 1200 out of 6000 frameworks suppressing offers
allocate() took 20.121897secs to make 1000 offers with 2400 out of 6000 frameworks suppressing offers
allocate() took 12.964302secs to make 1000 offers with 3600 out of 6000 frameworks suppressing offers
allocate() took 6.534221secs to make 1000 offers with 4800 out of 6000 frameworks suppressing offers
allocate() took 8953us to make 0 offers with 6000 out of 6000 frameworks suppressing offers
[       OK ] SlaveAndFrameworkCount/HierarchicalAllocator_BENCHMARK_Test.SuppressOffers/7 (106198 ms)


Mesos 1.3:

[ RUN      ] SlaveAndFrameworkCount/HierarchicalAllocator_BENCHMARK_Test.SuppressOffers/7
