A controller has $http that calls an api backend on Flask. I have some basic authentication and crossdomain is set. The first time it enters the cpuListCtrl controller the $http calls takes cca. ~14sec. The next time i visited the controller in angular it takes just 23ms. But every time i press the browsers refresh, back to ~14sec. Direct api call from browser also takes just 23ms. So my question is my does it takes so long, did i miss something, or where specific should i look?

EDIT: updated the code to reflect recent changes:

  var app = angular.module('RecycleApp', ['ngRoute', 'appControllers']);

    app.config(['$httpProvider', function($httpProvider) {

     $httpProvider.defaults.useXDomain = true;

     delete $httpProvider.defaults.headers.common['X-Requested-With'];

   }

  ]);



  app.config(['$routeProvider', function($routeProvider){

  $routeProvider

    .when(/cpu, {

        templateUrl:'static/js/partials/cpu.html',

        controller:'cpuCtrl'

    })

  }]);



  var appControllers = angular.module('appControllers', []);



  appControllers.controller('cpuCtrl', ['$scope','$http',

function($scope,$http){

    $http({

        url: 'http://SOME_IP/api/v1/cpus',

        method: 'POST',

        data: JSON.stringify({latitude:46.1948436, longitude:15.2000873}),

        headers: {Content-Type:application/json}

    })

    .success(function(data,status,headers,config){

        console.log(data.list);

        $scope.cpus = data.list;

    })

    .error(function(data,status,headers,config){

        console.log(something went wrong.);   

    })



 }]);

Server side:

@app.route('/api/v1/cpus', methods=[GET])

@cross_origin(origins='*', headers=(Content-Type))

def get_cpu_list():

    result = session.query(RecycleReUseCenter)

            .options(load_only(Id, CpuName))

            .all()

    return list_json(result)



@app.route(/api/v1/cpus, methods=[POST])

@cross_origin(origins='*', headers=(Content-Type))

def get_cpu_list_with_locations():

    content = request.get_json(force=True)

    given_latitude = content['latitude']

    given_longitude = content['longitude']



    result = RecycleReUseCenter.get_all_with_distance(given_latitude, given_longitude)

    return list_json(result)
