title: Can perf-stat results be generated from a perf.data file?
body: <p>When I want to generate performance reports using perf-stat and perf-report from the Linux tool suite <a href="http://code.google.com/p/kernel/wiki/PerfUserGuide">perf</a>, I run:</p>
  
  <pre><code>$ perf record -o my.perf.data myCmd
  $ perf report -i my.perf.data
  </code></pre>
  
  <p>And:</p>
  
  <pre><code>$ perf stat myCmd
  </code></pre>
  
  <p>But that means I run 'myCmd' a second time, which takes several minutes.  Instead, I was hoping for:</p>
  
  <pre><code>$ perf stat -i my.perf.data
  </code></pre>
  
  <p>But unlike most of the tools in the perf suite, I don't see a -i option for perf-stat.  Is there another tool for this, or a way to get perf-report to generate similar output to perf-stat?</p>
