title: Benchmarking programs on Linux
body: <p>for an assignment we need to benchmark our implementations with different optimizations and parameters. Is there a feasible way of benchmarking little programs on the linux command line (I know of time) with different parameters which gives me the time data as CSV or something similiar? Output could be something like:</p>
  
  <pre><code>Implementation      Time     
  A                    23s
  B with -O3 2Threads  15s 
  B with -O3 4Threads  10s 
  </code></pre>
  
  <p>I'm pretty sure that I've seen something like that on some professors slides but I cant remember who or when it was...</p>
