1. clone repo
2. install packages with govendor install +local
3. run it with go run salt.go or compile with go build salt.go and run with ./salt

/ gets you standard snippet that you can drop into your wp-config.php file

/env gets you format that you can drop into your .env file

/json gets you the salts with key-value in JSON format

We're only using the optimised fastest / safest versions of the function calls.

1. run app
2. siege one of the endpoints continuously (siege -c 250 -t2m -v http://localhost:8090 works nicely)
3. while siege is running, in another terminal, start the profile: go tool pprof http://localhost:8090
4. enjoy your data! See https://blog.golang.org/profiling-go-programs for more info on profiling
5. 48.9% syscall ;)
