bombardier is a HTTP(S) benchmarking tool. It is written in Go programming language and uses excellent fasthttp instead of Go's default http library, because of its lightning fast performance.
With bombardier v1.1 and higher you can now use net/http client if you need to test HTTP/2.x services or want to use a more RFC-compliant HTTP client.
Tested on go1.18 and higher.
You can grab binaries in the releases section. Alternatively, to get latest and greatest run:
Go 1.18+: go install github.com/codesenberg/bombardier@latest
bombardier [<flags>] <url>
For a more detailed information about flags consult GoDoc.
AFAIK, it's impossible to pass Host header correctly with fasthttp, you can use net/http(--http1/--http2 flags) to workaround this issue.
Example of running bombardier against this server:
> bombardier -c 125 -n 10000000 http://localhost:8080
Bombarding http://localhost:8080 with 10000000 requests using 125 connections
