A client approached me and asked if I can test and determine if an Ubiquiti 5 port Edgeport router (http://tinyurl.com/pba3sfz) would meet his needs. He needed a router for a site with an internet connection of 10 Mbps and another with 100 Mbps. The only technical requirement the client is looking for is that it has to support NAT (Network Address Translation).

When it comes to throughput testing, I always recommend staying away from the hard drive or storage in general. The primary reason is that the physical media may contribute a significant amount of latency for many reasons. In the past I have recommended utilities like iperf (https://iperf.fr/iperf-download.php) for this very reason.

One common methodology for measuring performance is to use a traffic generator or packet blaster and a receiving device simply calculates metrics and results. All traffic generators are not the same. I personally prefer ones that generate real packets that require a real response. I believe this two way conversation is more realistic rather than the one way blast.

No matter what tool you use it is critical that you document your methodology and equipment set up as well as your results. It is important to realize that every test will have a different result which is why I prefer to minimally conduct 5 tests. I discard the highest and lowest results and average the remaining three to get a better sample average. Different tools will report different results so do not expect different tools to report the same results since all tools perform tests differently. Some will use UDP, TCP and other might run directly over IP, not to mention there are different ways to calculate the results. The general rule is to stick with the same methodology and tool for your testing.

Once you learn how your tool of choice performs a test, you might want to check and see if you can change its behavior. For example you might be using UDP for your testing and want to use TCP, or your tool only send one TCP stream and you want more. And lastly, there is nothing wrong with running your tests with multiple tools.

In this example, I used NetScout’s Optiview XG’s (http://tinyurl.com/qdouval) Throughput Test with a Packet Sweep option. This is important to me since using different packet sizes gives me insight into how the device performs in different networks. The packet size range for most Ethernet networks is 64 to 1518 Bytes. All I can tell you is that your network will be somewhere in between the two values.
