You have thousands of derived files and you are lazy to clean wordpress installation.
To delete all media files with a single SQL code, simply use the code below.
I hope you can use it as a SQL query from the phpmyadmin panel.
DELETE FROM wp_postmeta WHERE post_id IN ( SELECT id FROM wp_posts WHERE post_type = 'attachment' ) ; # Second: DELETE FROM wp_posts WHERE post_type = 'attachment'You won't forget to edit the wp_posts and wp_postmeta keys according to the prefix on your own site, right? 🙂

As a Woocommerce user, if you have thousands of product ranges, unfortunately, you install many plugins for your cashier system and try to find a solution with Cache systems.
However, since Woocommerce is a system that appeals to the whole world, it is a system that compulsorily runs many unnecessary functions simultaneously. To alleviate this load, you can lighten the distribution of functions that you deem unnecessary, so that the features you do not use are not called by the system and save you speed / time.
The code I have given below into your theme's functions.php file Just add it, then you can delete the lines you want or you can add others. I'm sure you will gain a noticeable speed this way!
add_action( 'wp_enqueue_scripts', 'child_manage_woocommerce_styles', 99 ); function child_manage_woocommerce_styles() { //remove generator meta tag remove_action( 'wp_head', array( $GLOBALS['woocommerce'], 'generator' ) ); //first check that woo exists to prevent fatal errors if ( function_exists( 'is_woocommerce' ) ) { //dequeue scripts and styles if ( ! is_woocommerce() && ! is_cart() && ! is_checkout() ) { wp_dequeue_style( ' woocommerce_frontend_styles' ); wp_dequeue_style( 'woocommerce_fancybox_styles' ); wp_dequeue_style( 'woocommerce_chosen_styles' ); wp_dequeue_style( 'woocommerce_prettyPhoto_css' ); wp_dequeue_script( 'wc_price_slider' ); wp_dequeue_script( 'wc-single-product' ); wp_dequeue_script( 'wc-add-to-cart' ); wp_dequeue_script( 'wc-cart-fragments' ); wp_dequeue_script( 'wc-checkout' ); wp_dequeue_script( 'wc-add-to-cart-variation' ); wp_dequeue_script( 'wc-single-product' ); wp_dequeue_script( 'wc-cart' ); wp_dequeue_script( 'wc-chosen' ); wp_dequeue_script( 'woocommerce' ); wp_dequeue_script( 'prettyPhoto' ); wp_dequeue_script( 'prettyPhoto-init' ); wp_dequeue_script( 'jquery-blockui' ); wp_dequeue_script( 'jquery-placeholder' ); wp_dequeue_script( 'fancybox' ); wp_dequeue_script( 'jqueryui' ); } } }
