    Description

      When comparing perfasm outputs from bechmarks that run at different speeds, it is hard to disambiguate how the profile changes. Since in both "slower" and "faster" cases the counts add up to 100%, a distributed hotspot can show up at the same percentage level.

      Additionally, it is sometimes useful to see the raw counters, to ballpark how accurate the percents are.
