Ajax Calls

It has been brought to my attention by my managed hosting provider that there were 2454 calls from the plugin which can affect negatively the website performance. Is there a way to reduce them?. Here’s the breakdown
wp-content/wp-meta-data-filter-and-taxonomy-filter/classes/shortcodes.php
62: add_shortcode(‘mdf_search_panel’, array(__CLASS__, ‘show_search_panel’));
78: add_action(‘wp_ajax_mdf_search_panel’, array(__CLASS__, ‘mdf_search_panel’));
79: add_action(‘wp_ajax_nopriv_mdf_search_panel’, array(__CLASS__, ‘mdf_search_panel’));
1103: public static function mdf_search_panel(){
wp-content/wp-meta-data-filter-and-taxonomy-filter/js/front.js
1307: action: “mdf_search_panel”,

kind regards
