----------------------------------
The above commit {{42becf22f07831ef8c3d4fbc8c1b80eb9d5b959a}} was reverted due
to a regression caused by that version of the change. The following updated
patch reapplies it:

Optimized the generation of metrics snapshots.
Profiling of metrics generation revealed a large amount of time spent
in map operations. This patch does three things to mitigate this:
* Stores the metrics as an ordered map so that we only pay the price
of sorting when the metric is first added.
* Makes use of vectors instead of maps for intermediate objects,
which eliminates the need for another intermediate object.
* Hints when inserting into the returned map, reducing the cost of
insertion into that ordered container.

> times.
