You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: bytebuffer_timing_test.go
    path of file: ./repos/go-starter-kit/vendor/github.com/valyala/fasttemplate/vendor/github.com/valyala/bytebufferpool
    
    the code of the file until where you have to start completion: package bytebufferpool

import (
	"bytes"
	"testing"
)

func BenchmarkByteBufferWrite(b *testing.B) {
	s := []byte("foobarbaz")
	b.RunParallel(func(pb *testing.PB) {
		var buf ByteBuffer
		for pb.Nex
    
func BenchmarkBytesBufferWrite(b *testing.B) {
	s := []byte("foobarbaz")
	b.RunParallel(func(pb *testing.PB) {
		var buf bytes.Buffer
		for pb.Next() {
			for i := 0; i < 100; i++ {
				buf.Write(s)
			}
			buf.Reset()
		}
	})
}
