Those numbers are the time of translating a relatively short period of
time. Thus you hit granularity issues. If you want to get more accurate
timing, recalculate it with a longer sample:

  core show translation recalc <length>

You should probably use at least 10, and preferably 100 or 1000, to get
more accurate timing.
