Correct, it is a fake HTTP server, serving a real HTTP workload. This post is about comparing two different networking stacks (kernel vs DPDK) to see how they handle a specific (and extreme) HTTP workload. From the perspective of the networking stack, the networking hardware, and the AWS networking fabric between instances, these are real HTTP requests and responses.

Take a look at my previous article[1]. It is still an extreme/synthetic benchmark, but libreactor was able to hit 1.2M req/s while fully parsing the HTTP requests using picohttpparser[3].

From what I recall, when I played with disabling HTTP parsing in libreactor, the performance improvement was only about 5%.
