title: python unzip -- tremendously slow?
body: <p>Can somebody please explain the following mystery?</p>
  
  <p>I created a binary file of size ~37[MB]. zipping it in Ubuntu -- using the terminal -- took less than 1[sec]. I then tried python: zipping it programatically (using the zipfile module) took also about 1[sec].</p>
  
  <p>I then tried to unzip the zip file I created. In Ubuntu -- using the terminal -- this took less than 1[sec].</p>
  
  <p>In python, the code to unzip (used the zipfile module) took close to 37[sec] to run! any ideas why?</p>
