title: Rackspace cloud files: how to size containers to optimize performance?
body: <p>Rackspace cloud files uses a flat storage system using 'containers' to store files. According to Rackspace there is no limit to the number of files per container. </p>
  
  <p>My question is whether there is a best/most efficient number of files per container to optimize write/fetch performance. </p>
  
  <p>If I have tens of thousands of files to store, should they all go in a single giant container or partitioned into many smaller containers?  And if so, what is the optimal container size?</p>
