NOTE: I've just forked this from tsliwowicz/go-wrk to add the -insecure flag and ended up doing a bunch linting/styling, which I found just too much for a PR on his repo, drop him a star if this is useful for you
go-werk is a modern HTTP benchmarking tool capable of generating significant load when run on a single multi-core CPU. It builds on go language go routines and scheduler for behind the scenes async IO and concurrency.
It was created mostly to examine go language performance and verbosity compared to C (the language wrk was written in. See - https://github.com/wg/wrk). It turns out that it is just as good in terms of throughput! And with a lot less code.
The majority of go-werk is the product of one afternoon, and its quality is comparable to wrk.

This runs a benchmark for 5 seconds, using 80 go routines (connections)

The machine running go-werk must have a sufficient number of ephemeral ports available and closed sockets should be recycled quickly. To handle the initial connection burst the server's listen(2) backlog should be greater than the number of concurrent connections being tested.
golang is awesome. I did not need anything but this to create go-werk. I fully credit the wrk project for the inspiration and even parts of this text. I also used similar command line arguments format and output format.
