---------------------------------
Add some benchmark for Resources operators; i'll hep to evaluate the
improvement.
> Investigate performance improvements for 'Resources' class.

> Key: MESOS-4770
> URL: https://issues.apache.org/jira/browse/MESOS-4770
> Project: Mesos
> Issue Type: Improvement
> Reporter: Benjamin Mahler
> Assignee: Michael Park
> Priority: Critical
>
> Currently we have some performance issues when we have heavy usage of the
> {{Resources}} class. Currently, we tend to work around these issues (e.g.
> reduce the amount of Resources arithmetic operations in the caller code).
> The implementation of {{Resources}} currently consists of wrapping underlying
> {{Resource}} protobuf objects and manipulating them. This is fairly expensive
> compared to doing things more directly with C++ objects.
> This ticket is to explore the performance improvements of using C++ objects
> more directly instead of working off of {{Resource}} objects.
