API endpoint api/v4/users -Response time is very slow

Hi Team,

While creating the post request to the code in VB.net I have observed its taking more time to provide the response. could you please let me know what s wrong with my code.

API endpoint which I am consuming is : api/v4/users

Public Async Function InvokeAPIMatterMost(ByVal strJson As String, ByVal MethodName As String, ByVal AsyncService As String) As Threading.Tasks.Task

    Dim response As HttpResponseMessage
    Dim result As String = String.Empty
    Dim responseContent As String = String.Empty
    Dim ds As New DataSet

        Using client = New HttpClient()

            client.BaseAddress = New Uri(AsyncService & MethodName)
            client.DefaultRequestHeaders.Add("Authorization", "SECREATESGHSJJS")
            client.DefaultRequestHeaders.Accept.Add(New MediaTypeWithQualityHeaderValue("application/json"))

            Dim httpContent = New StringContent(strJson.ToString(), Encoding.UTF8, "application/json")
            httpContent.Headers.ContentType.CharSet = Nothing               
            response = Await client.PostAsync("", httpContent)
            result = Await response.Content.ReadAsStringAsync()

              ds = ReadDataFromJson(result)

                If ds IsNot Nothing AndAlso ds.Tables.Count > 0 Then
                    DsResult = ds
                End If


        End Using

    Catch ex As Exception
        ObjErr.Code = "1"
        ObjErr.Message = ex.Message
        ObjErr.Ex = ex
        response = Nothing
        result = Nothing
        responseContent = Nothing

    End Try

End Function

Its taking more than 1 to 2 mints to get the response.

please help me where its wrong.
