>
> After fixing MESOS-8418, there are still low hanging performance improvements
> that can be done to both the /containers and /monitor/statistics container
> usage metrics endpoints.
> * There is a lot of copying of {{ResourceUsage}} protobufs, the primary cost
> being copying the embedded executors and tasks in the protobuf. See the
> attached flamegraph.
> * Adoption of jsonify instead of constructing JSON objects will improve
> performance.
> There are a variety of less trivial improvements as well.
