http-perftrace's Introduction

http-perftrace

Experiment with the Go httptrace library building a simple CLI tool to output HTTP performance for a given URL. It's basically like siege or something, but written in Go, and much much simpler.

TODO

Double check hooks in httptrace.ClientTrace and their correct use in this tool
Provide some more useful output at the end, maybe 95th percentiles for example
Add colours
Add interval between requests (or random interval)
Add linter, tests, etc
