Subject: Wildly different output sizes between subsequent perf record runs.
Date: Fri, 3 Nov 2017 18:57:01 -0700 [thread overview]
Message-ID: <CABYXEkvrMhd9+P01k94AE97YHooDcs8Nxn4UfuvKfzzq88foVA@mail.gmail.com> (raw)
If I do subsequent runs of 'perf record', both of which are identical,
I sometimes get wildly different output sizes.

The binary did the same amount of work, and took the same amount of
time to execute.
This is with using perf from Ubuntu LTS.
