--------------------------------------
Summary: Avoid dirtying the DRF sorter when allocating resources.
Key: MESOS-9249
URL: https://issues.apache.org/jira/browse/MESOS-9249
Project: Mesos
Issue Type: Improvement
Components: allocation
Reporter: Benjamin Mahler
Assignee: Benjamin Mahler
The perf data that [~mzhu] provided revealed that when there are many
frameworks, the {{DRFSorter::sort()}} function ends up dominating the time
spent during an allocation cycle.
To improve performance, it's possible to avoid dirtying the sorter so that it
remains sorted throughout the entire allocation cycle.
