Failed experiment: strings.join vs buffer.WriteString

gistfile1.txt

	start := time.Now()

	/*
		var buffer bytes.Buffer
		for _, x := range v {
			buffer.WriteString(x)
			buffer.WriteString("::")
		}

		test := strings.ToLower(buffer.String()) */
	test := strings.ToLower(strings.Join(v[:], "::"))
	t := time.Now()
	elapsed := t.Sub(start)

	f, _ := os.OpenFile("/tmp/joincat", os.O_APPEND|os.O_WRONLY, 0600)
	e := fmt.Sprintf("%d\n", elapsed.Nanoseconds())
	f.WriteString(e)

Surprisingly, strings.join() was slightly more performant than buffer.WriteString. Oh well.
