Comment (by prettyboymp):

 I've been running into performance issues with an image heavy site on a
 setup with the uploads dir mounted on networked storage.  I traced it down
 to the `wp_mkdir_p` and found this ticket.  I've been running @kovshenin's
 31066 patch for a few days now and haven't had any issues since.

 One improvement that I think could be made to help even further improve
 performance for plugins that use `wp_upload_dir()` would be to store a
 static result from it's `wp_mkdir_p` call since PHP won't cache the
 `file_exist` calls.
