Is there a better way? from ...
What's the Fastest way to get a large number of files (relatively small 10-50kB) from Amazon S3 from Python? (In the order of 200,000 - million files).

I am writing a script using boto and Python to automatically launch an Amazon EC2 instance and interact with it using SSH.
