> Key: MESOS-3051
> URL: https://issues.apache.org/jira/browse/MESOS-3051
> Project: Mesos
> Issue Type: Bug
> Components: allocation
> Affects Versions: 0.22.1
> Reporter: James Peach
> Assignee: Joerg Schad
>
> Testing in an environment with lots of frameworks (>200), where the frameworks permanently decline resources they don't need. The allocator ends up spending a lot of time figuring out whether offers are refused (the code path through {{HierarchicalAllocatorProcess::isFiltered()}}.
> In profiling a synthetic benchmark, it turns out that comparing port ranges is very expensive, involving many temporary allocations. 61% of Resources::contains() run time is in operator -= (Resource). 35% of Resources::contains() run time is in Resources::_contains().
> The heaviest call chain through {{Resources::_contains}} is:
> {code}
> Running Time Self (ms) Symbol Name
