    117117All EC2 instances were created to the same availability zone (us-east-1d). The setup of 100 client instances took ~4 minutes with 34 threads running Fabric (~3 runs per thread).

     140'''Analysis'''
     141
     142100 clients connecting at the same time is clearly above the capabilities of ''m1.small'' instance in EC2. Also, the data transfer statistics are skewed because of the long client connection delays, which create a "tail" of clients that raise the average bandwidth numbers because they get a larger proportion of server's resources for their use.
