Dear Mesos team, We are now trying to use Mesos to manage container cluster in large scale. During our test, we found some performance issue about Ranges value subtraction. The current implementation is low-efficient and causes serious overhead to Mesos allocator. Joseph Wu has helped to file a jira to track this issue:https://issues.apache.org/jira/browse/MESOS-5425. We have prepared a fix by re-implementing the Ranges subtraction using IntervalSet data type and we hope to get assignment of this jira to contribute our fix back to Mesos. Thank you so much!
