FTDC timeseries data for both the recording and playback phases:

• A-C: record phase
  • A-B: 8 threads each inserting 500 k empty documents into a single collection in batches of 1000
  • B-C: 1 thread doing a collection scan

• D-G: playback phase
  • D-F: inserts - playback of A-B. Note how the rate of inserts drops about halfway through, by about a factor of 2, and the inserts don't end until F, overlapping the reads, unlike during the record phase
  • E-G: reads - playbck of B-C. Note that this appears to begin at about the right time corresponding to B during the recording, but unlike during the recording, on playback this begins before the inserts have ended.

• H-I: unexpected second playback (TOOLS-1497)
