How to beat wordpress loading speed with multiple taxonomies?

Question

memcached

Hello. I ran into a problem when there are a lot of taxonomies in the system (I have more than 1000 of them), the site speed dropped by ~3 seconds (they were taken from woocommerce, because in it global attributes are created by separate taxonomies pa_attr1, pa_attr_2, ... pa_attrN, and taxonomies are registered on almost every back- and front-end page, i.e. woo does in wp-content/plugins/woocommerce/includes/class-wc-post-types.php (209)

$attribute_taxonomies  = wc_get_attribute_taxonomies();
foreach ( $attribute_taxonomies as $tax ) {
          register_taxonomy( $name, apply_filters( "woocommerce_taxonomy_objects_{$name}", array( 'product' ) ), apply_filters( "woocommerce_taxonomy_args_{$name}", $taxonomy_data ) );
}

Below is an example of loading the main page of the site before and after disabling this cycle of taxonomy registrations:


How can I resolve this moment? There was an idea to cache the result of register_taxonomy for each of them in memcache, but the function returns $taxonomy_object, as I understand it, it won’t be possible to cache it like that and getting into the wp core is not the best solution? Or are there other ways to get around this? Thank you.
