EC2 Network bandwidth performance tests!

So using the post I did below, I had some fun testing the network capabilities of some different instances. For my tests, I first tried using micros in the same AZ/region/VPC using private IP, then public IP, then I tried the big boy r3.8xlarge instances (which offers 10 Gigabit speeds), then I tried to bandwidth test these instances across the ocean (Oregon to Sydney regions).

–all instances are using Amazon Linux
–all instances had enhanced networking enabled (enhanced networking not offered with micros)

Here are my results! (I encourage you to do your own testing, because 1 its fun 2 the internet has many hops and network traffic can vary wildly from one day to the next)

Super local, same AZ/region/VPC (best performance you can get)
t2.micro to t2.micro within Oregon private IP: 3.00 Gbits/sec (nice for a micro!)
t2.micro to t2.micro within Oregon public IP: 1.16 Gbits/sec
r3.8xlarge to r3.8xlarge within Oregon private IP: 9.85 Gbits/sec (SICK)
r3.8xlarge to r3.8xlarge within Oregon public IP: 5.09 Gbits/sec

Across the Ocean bro!
t2.micro to t2.micro Oregon to Sydney public IP: 68.1 Mbits/sec
r3.8xlarge to r3.8xlarge Oregon to Sydney public IP: 116 Mbits/sec

What does this show/mean? First off, if you need to get the best speeds, you are best off putting your instances right next to each other in the same AZ same VPC same subnet and using private IPs. However, if you need to go across regions, speeds are still decent.
