Tests of S3--EC2 transfer speed using curl have shown that gigabit
ethernet speeds can be reached between nodes but only when multiple
transfers are overlapped. See:

What sort of performance hit is there for using S3 vs. a local cluster?
In my experience on EC2 using Hadoop, S3-backed HDFS is 25-33% slower
than disk-backed HDFS. That was using 0.14.x, however, so it might be
better now...
