… is not what this is about. I was however curious how Pen performs compared to other open source load balancers. All load balancers I could think of in Raspbian were installed on the trusty RPi2 and configured to withstand the same torrent of traffic I use to test Pen.
The result can be seen below. In the interest of keeping crazies out, the “other” load balancers have been anonymized. This is a very simple synthetic test and the results may vary a lot depending on the test conditions. It is however nice to see that:
– Pen had the highest maximum throughput, measured in requests per second
– Pen supported the highest concurrency of all tested load balancers
In the chart below, X is the number of concurrent requests and Y is the number of requests per second. More is better. No line means that the load balancer failed.
