title: Pipe VS Temporary File on RAM
body: <p>This is the return of a classic question : for transferring datas between two process, should we use "pipe" or "temporary file". </p>
  
  <p>It was debated here, for reference : <a href="https://stackoverflow.com/questions/6977561/pipe-vs-temporary-file">Pipe vs. Temporary File</a></p>
  
  <p>Now, considering only UNIX system, that can use tmpfs or ramfs (RAM based filesystem), we can write temp files really fast.</p>
  
  <p>In my specific case, data is 100Ko PNG image file.</p>
  
  <p>What option would you prefer ?</p>
