graph diffs from perl flamegraph #328

I use the same perf.data

  1. when using perl flamegraph, the total samples shows 295730188910
  2. when using rs flamegraph, the total samples shows 36277
  3. when using perf report, it shows Samples: 36K of event cycles, Event count: 295730188910

that makes graphes look diff results with perl flamegraph is more closely match the percentages shown in perf report

You might want to take this up with inferno -- flamegraph is a fairly thin wrapper over perf + inferno.
