Has the download speed issue been solved? I got the following results using s3sync from an EC2 instance. I am using FC6 with ruby version 1.8.5.

22MB file using s3cmd
Upload - EC2 => S3  = 6 MB/s
Download - S3 => EC2  = 1.4 MB/s

22MB file using WGET
Download S3 => EC2 = 11MB/s

I can live with the upload speed of 6MB/s. However, the download speed is pretty slow. Has anyone found a better way to go about this?
