I've written an ajax call to get some user specific content. But I found that the response of the ajax call is very slow. Indeed, I found that this is due to the slow response of the controller class. The controller class takes at least 2 seconds to give a empty json respnse while the controller is just a simple controller to handle the ajax call.

namespace Vendor\ModuleName\Controller\Program;

class TestAjax extends \Magento\Framework\App\Action\Action {

    public function __construct(
    \Magento\Framework\App\Action\Context $context
    ) {

     * Forgot customer account information page
     * @return \Magento\Framework\View\Result\Page
    public function execute() {
        $testing= null;

        $arr = array('testing' => $testing);
        $jsonData = json_encode($arr);
        $this->getResponse()->setHeader('Content-type', 'application/json');

  • Disabling the cache has a sense for some development tasks only & Caching definitely should be enabled in production mode – MagikVishal Jun 16 '16 at 5:27
  • Are you saying this controller action is specifically much slower than all other controllers on the same install? – Peter O'Callaghan Jun 16 '16 at 8:36
  • Try do it more in magento way, like this, maybe it will be faster: magento.stackexchange.com/questions/99358/… – Bartosz Kubicki Dec 31 '16 at 10:52

Yes, I have also use the Ajax in magento2 and getting very slow response from controller

My Code is:

var param = {
    dDate: datem,
    user: <?php echo json_encode($username); ?>,
    courseid: <?php echo json_encode($courseid); ?>
 //var param = 'ajax=1&date='+datem+'&arr123='+jQuery.parseJSON(<?php echo json_encode($timeArr2,true); ?>);
 jQuery.ajax( {

url: '<?php echo $storeManager->getStore()->getBaseUrl(); ?>/wlcms/index/',
data: param,
type: 'GET',
dataType: 'json'

}).done(function(a) { 

    // alert(json_decode(a));
