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
