Title: Very slow loading Last modified: June 15, 2020 --- # Very slow loading * Resolved [philip033](https://wordpress.org/support/users/philip033/) * (@philip033) * [5 years, 11 months ago](https://wordpress.org/support/topic/very-slow-loading-8/) * Hello, * After purchasing ACF, I installed ACF Extended, I created around 3700 taxonomies for classification purposes. The problem is that, when I want to modify a WooCommerce product, the opening time is 71s, it is extremely slow, when I deactivate ACF Extended, the loading time is 2s. This means that the extended plugin is not optimized. Can you tell me if there is a way to use the ACF Extended plugin without having such long loading times? * Thanking you for your help * Query : * SELECT DISTINCT t.*, tt.* FROM 5fgr47wp_terms AS t LEFT JOIN 5fgr47wp_termmeta ON ( t.term_id = 5fgr47wp_termmeta.term_id AND 5fgr47wp_termmeta.meta_key=’order’) INNER JOIN 5fgr47wp_term_taxonomy AS tt ON t.term_id = tt.term_id WHERE tt.taxonomy IN (‘product_cat’) AND ( ( 5fgr47wp_termmeta.meta_key = ‘order’ OR 5fgr47wp_termmeta. meta_key IS NULL ) ) ORDER BY 5fgr47wp_termmeta.meta_value+0 ASC, t.name ASC * Caller : WP_Term_Query->get_terms() * Component : * Plugin: acf-extended * Rows : 2710 * Time : 0,0551 Viewing 13 replies - 1 through 13 (of 13 total) * Plugin Author [Konrad Chmielewski](https://wordpress.org/support/users/hwk-fr/) * (@hwk-fr) * [5 years, 11 months ago](https://wordpress.org/support/topic/very-slow-loading-8/#post-12987926) * Hello, * Thanks for the feedback. Just to be precise, you created 3700 terms, not taxonomies, right? If that’s the case, in which taxonomy? The native `product_cat` Woocommerce taxonomy? * Can you please tell me on which page do you have that slow down? Admin Product Edit? Front Product Single? * If the page is in admin, is there any ACF fields there? If yes, which one (Name, type, data)? * The debug log you shared is saying the query took 0.05 seconds to execute, so it’s most likely not tied to that one. Can you please share a full screenshot of the Query Monitor? * Regards. * Thread Starter [philip033](https://wordpress.org/support/users/philip033/) * (@philip033) * [5 years, 11 months ago](https://wordpress.org/support/topic/very-slow-loading-8/#post-12991008) * Hello, * Sorry for not being specific enough. The 3700 are product categories (Woocommerce- > products -> product categories). The page that slows down is when I click on product -> modify, not on quick edit. All this is in the admin part in the backend. Yes I have ACF fields, there are 29, 6 drop-down lists, 6 text fields, 3 date fields, 3 checkbox fields, 1 image field, 1 gallery field, 1 button group field, 6 groups with each about 150 fields of taxonomy terms. I have no slowdown elsewhere, in the backend or the frontend, except when I want to modify a product in the admin part. I specify that I am on a very good server with good resources. I managed to speed up loading (I gained 30s out of 70s) with the code you give on wordpress to deactivate modules: How to disable specific ACF Extended modules?( Dynamic Post Types, Taxonomies, Options Pages etc…) * thanking you for your help * Thread Starter [philip033](https://wordpress.org/support/users/philip033/) * (@philip033) * [5 years, 11 months ago](https://wordpress.org/support/topic/very-slow-loading-8/#post-12991032) * [Screen1](https://builders.mailex-sites.ovh/wp-content/uploads/2020/06/Capture2.png) [Screen2](https://builders.mailex-sites.ovh/wp-content/uploads/2020/06/Capture3.png) * Plugin Author [Konrad Chmielewski](https://wordpress.org/support/users/hwk-fr/) * (@hwk-fr) * [5 years, 11 months ago](https://wordpress.org/support/topic/very-slow-loading-8/#post-12992530) * Hello, * The problem come from the “Taxonomy Terms” fields you have in your Product Edit screen. If you temporarily disable the field group that contain those fields, you’ll see a performance improvement. This is why when you disable ACF Extended, performance gets better, because the “Taxonomy Terms” field doesn’t exists anymore. * The thing is, Taxonomy Terms field load all terms of the allowed taxonomy on page load. In your case, the taxonomy Product Category has 3.7k terms. A solution is to use the field as a Select and use Asynchronous Load setting. But the Async Load setting isn’t effective for the moment, I have to implement it first. it’s on the roadmap. * Meanwhile, a workaround is to use the native ACF “Taxonomy” field, which can be used as a Multi Select and has a built-in Asynchronous Load setting. * Note: Enabling/Disabling modules should not alter performance. I don’t know which modules you disabled, but it is most likely an unrelated side effect. * Regards. * Plugin Author [Konrad Chmielewski](https://wordpress.org/support/users/hwk-fr/) * (@hwk-fr) * [5 years, 11 months ago](https://wordpress.org/support/topic/very-slow-loading-8/#post-12995440) * Hello, * I just commited an update for the Taxonomy Terms field which includes a working Asynchronous Load setting. It will be published in the next patch. * In the meantime, you can download the file and replace it in `acf-extended/includes/ fields/field-taxonomy-terms.php`. Here is the new version: [https://raw.githubusercontent.com/acf-extended/ACF-Extended/master/includes/fields/field-taxonomy-terms.php](https://raw.githubusercontent.com/acf-extended/ACF-Extended/master/includes/fields/field-taxonomy-terms.php) * Then, you’ll be able to set the field Type as “Select” and use the “Use Ajax to Lazy Load Values” setting in your Taxonomy Terms fields.
