Ways to load admin-ajax faster without initializing all plugins?

by brandNewWPUser   Last Updated November 01, 2017 06:08 AM

I'm facing a problem with wp ajax performance. I'm initializing an ajax call from my javascript side but the response takes 3-5 secs to come back. I understand that admin ajax call has to load the whole wp core and that would definitely be a performance hit for us.

Is there a way to still use the admin ajax call, but without loading all plugins? Essentially in my php api, I'm only using some values from wp-config. Or is there any better ajax suggestions given my use case? Is it possible to use regular rest API(without going through admin-ajax) but could still use the values from wp-config?

Here is my js code(ajax.js):

        url: ajax_object.ajax_url,
        data: {
            action: 'geo_ip_api'

        type: 'POST',
        success: function (output) {
        error: function (xhr, ajaxOptions, thrownError) {

Here is my php api(api.php):

function geo_ip_api(){
global $bannerRequiredRegions;
global $ipBlackList;
$isInEU = 'null';
$ipAddress = get_ip_address();
if(!in_array(strtolower($ipAddress), array_map('strtolower', $ipBlackList)))
        require_once 'HTTP/Request2.php';
        /* retrieving values from wp-config */
        $api_url = GEO_API_URL;

        $request = new Http_Request2($api_url);
        $url = $request->getUrl();

        //sending HTTP request logic here. No dependency on wordpress
    catch (Exception $ex)
        //TODO: put log here

echo $isInEU;


Any help appreciated! Thanks in advance. I've searched lots of post and none of those could answer my question.
