go语言中rows.Next性能问题

下面代码中 因为数据也不算太大2W多条，但是rows.Next() 竟然执行了1分多钟，我换回C#10来秒，这让我很不理解，有大神能提点下吗？不胜感激 func queryLineInfo() string { loginfo(log_info, log_project, "数据查询开始!") rows, err = QuerySql(sqlstr) loginfo(log_info, log_project, "数据查询结束!") if err != nil { rows.Close() //fmt.Println("数据库查询失败", err) get_lineinfo.Rescode = "0000" get_lineinfo.Resmsg = "数据库查询失败！" } var databuff []get_lineinfo_buff loginfo(log_info, log_project, "数据组织开始!") for rows.Next() { var buff get_lineinfo_buff err = rows.Scan(&buff.LineNo, &buff.LineName, &buff.Station_id, &buff.Station_Order, &buff.Station_Name, &buff.IsUpDown, &buff.Status, &buff.Price, &buff.StartTime, &buff.EndTime) if err != nil { rows.Close() loginfo(log_error, log_project, "rows.Scan失败："+err.Error()) get_lineinfo.Rescode = "0002" get_lineinfo.Resmsg = "数据解析失败！" } else { get_lineinfo.Rescode = "0001" get_lineinfo.Resmsg = "数据获取成功！" databuff = append(databuff, buff) } } rows.Close() get_lineinfo.Data = databuff loginfo(log_info, log_project, "JSON转换开始!") if jsonstr, err = json.Marshal(get_lineinfo); err != nil { fmt.Println("Json", err) } loginfo(log_info, log_project, "JSON转换结束!") return string(jsonstr) }
