Go でのマップ初期化の「make」と「{}」の間にパフォーマンスの違いはありますか?

<code class="go">var myMap map[string]int
myMap = map[string]int{}</code>

<code class="go">myMap = make(map[string]int)</code>

<code class="go">package bench

import "testing"

var result map[string]int

func BenchmarkMakeLiteral(b *testing.B) {
    var m map[string]int
    for n := 0; n < b.N; n++ {
        m = InitMapLiteral()
    }
    result = m
}

func BenchmarkMakeMake(b *testing.B) {
    var m map[string]int
    for n := 0; n < b.N; n++ {
        m = InitMapMake()
    }
    result = m
}

func InitMapLiteral() map[string]int {
    return map[string]int{}
}

func InitMapMake() map[string]int {
    return make(map[string]int)
}</code>
