> 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.
