> Poor allocator performance with labeled resources and/or persistent volumes

> Key: MESOS-4833
> URL: https://issues.apache.org/jira/browse/MESOS-4833
> Project: Mesos
>  Issue Type: Bug
>  Components: allocation
>Reporter: Neil Conway
>Assignee: Zhitao Li
>Priority: Blocker
>  Labels: mesosphere, resources
> Fix For: 0.28.0
>
>
> Modifying the {{HierarchicalAllocator_BENCHMARK_Test.ResourceLabels}} 
> benchmark from https://reviews.apache.org/r/43686/ to use distinct labels 
> between different slaves, performance regresses from ~2 seconds to ~3 
> minutes. The culprit seems to be the way in which the allocator merges 
> together resources; reserved resource labels (or persistent volume IDs) 
> inhibit merging, which causes performance to be much worse.
