This is a utility CLI and proof of concept for more quickly transferring files from local disk to HP Cloud Object Storage.
There are a couple prerequisites in PHP and cURL. If you are on a Mac you already have everything you need. On Debian flavored Linux you can use apt-install php5-cli php5-curl to install them. If you are on Windows you're out of luck. There's a bug.
Once you have PHP, download copy-to-hpcloud and give it executable permissions (e.g., chmod +x copy-to-hpcloud). Execute copy-to-hpcloud for the options and use.
Transferring lots of smaller files over the Internet can be slow. This is because many tools create a new connection to transfer each file. This means to transfer each file a connection is negotiated and then TCP slow-start kicks in. This does not perform well on short lived connections which is what these are.
Instead, this application opens a connection and sends lots of files over it. This removes the negotiation and start up time making for faster transfers.
Note, there is still room for improvements in transferring files. For example, with lots of small files this method doesn't come close to saturating a network connection. In addition to fewer connections, transferring files in parallel could speed things up.
I wrote this in PHP because the HP Cloud PHP bindings already support connection sharing via cURL.
