Question: Did the EBS volume matter?

There isn't any mentioning of EBS in this benchmark. Given that a gp2 volume is limited to 250 MB/s, the bottleneck on a CPU that supports 10-gigabit network is more likely to be the hard-drive I/O.

@dvassallo Do you have information about the EBS volume types you've used? Is hard drive I/O not a factor?
