[Amazon S3 Transfer Acceleration](http://docs.aws.amazon.com/AmazonS3/latest/dev/transfer-acceleration.html) enables fast, easy, and secure transfers of files over long distances between your client and an S3 bucket. And [aws-sdk](https://github.com/aws/aws-sdk-ruby) has allowed us to enable this feature in version 2.3.0 (more detail is [here](https://github.com/aws/aws-sdk-ruby/pull/1163)). You can now pass a configuration option (:use_accelerate_endpoint) when config Paperclip with S3. You can enable the [Amazon S3 Transfer Acceleration](http://docs.aws.amazon.com/AmazonS3/latest/dev/transfer-acceleration.html) by set this option: ```:use_accelerate_endpoint => true``` [fixes #2291]
