However, as these devices should, in theory, out-perform the other models, I should be able to discern encryption and decryption throughput separately for the EdgeRouter Lite and EdgeRouter X I may explore this in the future once I have something that can push more data than these devices are capable of, which should allow me to measure them independently. Unfortunately, as I am limited by the overall performance for just one of the EdgeRouter 4’s, I wont really know if the throughput is capped by encryption or decryption performance So for the purposes of this test, I will assume the value I establish will be the same each way for the EdgeRouter 4.
The routers themselves are initially at the factory default settings other than rudimentary interface configs, some static routes, hardware offloading (more on that later) and the configuration components needed to establish an encrypted GRE tunnel using IPsec. The physical layout I’ve used for the testing is pretty straightforward in that it’s two Dell R210ii servers directly attached to a router each, with another link between the two routers, as illustrated below. So whilst this article will mainly focus on IPsec, I will be including some general observations/comparisons between the devices too which may be informative to some people.Īccording to Ubiquiti’s data sheets, the EdgeRouter 4 should be the beefier device, so it seemed logical to use the pair I have to establish a base number which I can compare the other two models against.
Part of my lab setup will involve provisioning a couple of IPsec tunnels between the lab and my home network. I thought a good place to start would be to compare how well these different models perform in terms of IPsec throughput and overall CPU usage at the same time. These new devices, along with an EdgeRouter Lite loaned to me for this article by Dom at LoveServers, puts me in a reasonably good position to do some performance testing between these different models of EdgeMAX routers. I’ve been working on setting up a lab environment for myself and decided to pick up a couple of Ubiquiti’s EdgeRouter 4 routers to act as my core routing devices, along with an EdgeRouter X to act as my out-of-band router.
