Description

The current art summary includes a time tracker with various CPU/real-time measurements. The new TimeTracker service will do something similar, but only with real-time measurements. We should see if these two summaries can somehow be merged.

A meeting will be scheduled to identify whether TimeTracker can / should be changed to support the worthwhile aspects of the current "TimeReport" summary (and what those worthwhile aspects are).

I'm seeing several (12) getrusage system calls at some point during event processing when I only have and output module specified.
If they can be eliminated or reduced, I may be able to get a significant performance gain.

Per discussion at the stakeholders meeting on 5/19/2017, the job-level CPU time will still be captured, as that is helpful. However, the frequent CPU usage capturing at the event-level will be removed. If users want more detailed timing information, they should enable the TimeTracker service (which gives detailed per-module wall-clock times), or use a profiler (e.g. allinea).

Implemented with commit art:e75def7b.
