Queries load slowly since the latest update

Good morning,

I encounter an issue of performance since the latest update of WooCommerce (version 3.5.1).

In fact, when I uninstall the plugin, the site load the content correctly but with the plugin unable, the content is load slowly.

I use Ajax and WordPress API to load the content but The problem is not only on a Shop or product page but also in a listing of Custom Post Type page.

Thanks for your help and have a nice day !
