Comparing Implementations with compare

Problem

You have multiple implementations of the same idea and want to know which one is faster.

Idiom: Comparing Benchmarks by Median Time

The compare function runs micro for each benchmark, sorts the results by median time (p50), and computes a relative ratio against the fastest implementation.

var {*} = import(
	"slug.time",
	"slug.benchmark",
)

var slow = fn() { sleep(10) }
var fast = fn() { sleep(5) }

var report =
	compare([
		{name: "slow version", fun: slow},
		{name: "fast version", fun: fast},
	],
	)

report /> printCompareReport

The fastest benchmark is shown as x1, with slower implementations reported relative to it.
