并且序列化之后会举办一次数据拷贝：
- func (cfg *frozenConfig) Marshal(v interface{}) ([]byte, error) {
- stream := cfg.BorrowStream(nil)
- defer cfg.ReturnStream(stream)
- stream.WriteVal(v)
- if stream.Error != nil {
- return nil, stream.Error
- }
- result := stream.Buffer()
- copied := make([]byte, len(result))
- copy(copied, result)
- return copied, nil
- }
既然要用 buffer 那就一路吧^_^，这样可以镌汰多次内存分派，下读取 http.Response.Body 之前必然要记得 buffer.Reset()， 这样根基就已经完成了 http.Request.Body 和 http.Response.Body 的数据读取优化了，详细结果等上线跑一段时刻不变之其后查察吧。
结果说明
上线跑了一天，来看看结果吧。
