Sorted index query time is same as unsorted index

Elastic Stack Elasticsearch
1

I have a sorted index based on profile_created_time.
When I query to the index when index sorting enabled and disabled . Query time is same.

Can someone help what is wrong with my query.

{
  "size": 20,
  "from": 0,
  "sort": [
    {
      "profile_created_time": {
        "order": "desc"
      }
    }
  ],

        "bool": {

              "friend": {
                "status": "online"
              }
            }
          ]
        }
      },
      "must": {
        "dis_max": {
          "queries": [
            {

                        }
                      }
                    }
                  }
                }
              }
            },

                ],
                "query": "andy"
              }
            }
          ],
          "tie_breaker": 0
        }
      }
    }
  }

first, can you check that the index sort order is the same in the mapping?

second, you can use the profile API - or to simplify things, use the kibana profiler, which leverages that API, to check where the time of your query is spent.
