----------------------------------
Assignee: Neil Conway
> 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
> Assignee: Neil Conway
> Priority: Blocker
> Labels: perfomance

> 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:
> {noformat}
> [ 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
