Title: admin-ajax.php Last modified: August 31, 2016 --- # admin-ajax.php * [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/) * I really like this plugin, but calling admin-ajax.php is causing posts and pages to take an extra 0.5s to load. Might it be possible to use an alternative, lighter method? * [https://wordpress.org/plugins/post-views-counter/](https://wordpress.org/plugins/post-views-counter/) Viewing 11 replies - 1 through 11 (of 11 total) * Thread Starter [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233626) * Hmm, interestingly, although I’m using a caching plugin, for which you recommend the javascript method of recording post views, it looks as though the PHP method works fine when using Comet Cache. * Plugin Author [dFactory](https://wordpress.org/support/users/dfactory/) * (@dfactory) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233831) * Good to know about Comet Cache. * When it comes to admin-ajax.php, it should not slow down ajax requests – PVC does nothing in the admin (except dashboard widget), and is used to fire a simple function. Maybe there’s another factor in this. * Regards, Bartosz / dfactory team * Thread Starter [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233841) * Unfortunately, there’s no other factor involved in the `admin-ajax.php` issue. I have spent quite some time diagnosing this, and have turned off other plugins to make sure. The most helpful resource I found is here: [https://www.keycdn.com/blog/admin-ajax-php-slow/](https://www.keycdn.com/blog/admin-ajax-php-slow/) * When the plugin is active, `admin-ajax.php` is called, and that adds another 0.5 seconds to the page loading time. When the page otherwise loads in around 1 second, that means an additional 50%. * Obviously, if the PHP method continues to work with Comet Cache, then I’ll stick with that. But you might want to take a look at the above article just the same. * Plugin Author [dFactory](https://wordpress.org/support/users/dfactory/) * (@dfactory) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233843) * If you can enable the JS mode we’d like to take a look. * Thread Starter [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233873) * OK! JS mode is now enabled, and the site is [https://webby-books.com/](https://webby-books.com/) I have been using GTMetrix to see what’s going on: [https://gtmetrix.com/](https://gtmetrix.com/) * Plugin Author [dFactory](https://wordpress.org/support/users/dfactory/) * (@dfactory) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233886) * Looks like in most cases you have only one admin-ajax.php request per page. * So I believe the influence on loading time is related to the fact that admin- ajax.php is called at all, not that PVC is doing that. * If there was a different plugint doing Ajax on page load, you would have the same result probably. * The time required to run admin-ajax.php depends on number of things like your server enviroment, number and quality of plugins used, current theme, etc. * I may tell you we have a plan to provide “slim” ajax mode for PVC, not relying on admin-ajax, that will load only minimal resources (and make the request much faster). However this would be an experimental ferature – according to any WP guidlines Ajax calls should run just as it is now in PVC. * Thread Starter [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233899) * > Looks like in most cases you have only one admin-ajax.php request per page. * Yes, that’s right. * > So I believe the influence on loading time is related to the fact that admin- > ajax.php is called at all, not that PVC is doing that. * But PVC is what is calling admin-ajax.php * You can tell that from following the article to which I referred above ([https://www.keycdn.com/blog/admin-ajax-php-slow/](https://www.keycdn.com/blog/admin-ajax-php-slow/)). * I can also tell that is true because if I turn off PVC, admin-ajax.php is never called. * > I may tell you we have a plan to provide “slim” ajax mode for PVC, not relying > on admin-ajax, that will load only minimal resources (and make the request > much faster). * I am certainly interested in trying that out. * Plugin Author [dFactory](https://wordpress.org/support/users/dfactory/) * (@dfactory) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233901) * The speed of admin-ajax.php doesn’t depend on our plugin but on your WordPress install. * The article is great as it may help you optimize your site, but it’s unrelated to PVC. * Just fun fact about admin-ajax speed – if you enable WooCommerce for example, the speed might jump from 500ms to 2 seconds or so : ) * Thread Starter [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233902) * Yes, I understand that: that’s the problem with admin-ajax.php: it calls stuff from the whole site. That’s why I don’t want admin-ajax.php to run at all. * Since PVC is the only thing calling admin-ajax.php, the purpose of opening this thread was to see if you can find a way to have PVC work without calling it. Your proposed “slim” ajax mode sounds like what I was hoping for. * Plugin Author [dFactory](https://wordpress.org/support/users/dfactory/) * (@dfactory) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233905) * We don’t always like admin-ajax.php too (however it has some imporant advantages). * We’ll work on a slim version, we’ll se how it works. * Thread Starter [KTS915](https://wordpress.org/support/users/kts915/) * (@kts915) * [10 years, 2 months ago](https://wordpress.org/support/topic/admin-ajaxphp-6/#post-7233908) * Thank you!
