What do you mean "very long article"? You could have used "extensive" or something ;) Anyway, what I've seen when comparing the performance of tools, is that Artillery, which is running on NodeJS, is perhaps the wors performer of all the tools I've tested. I don't know if it's because of NodeJS or that Artillery in itself isn't a very performant piece of software (It also consumes a lot of memory, btw). If you want the highest performance, there is one tool that runs circles around all others (including k6), and that is wrk - https://github.com/wg/wrk https://github.com/wg/wrk - very cool piece of software although it is lacking in terms of functionality so mostly suitable for simpler load testing like hammering single URLs. (I don't know how fast wrk2 is, haven't benchmarked it)
