Hello,
Maybe you had a peak load at a time when you had a lot of visitors. The theme itself does not put any load on your site. But when you perform some actions on the site, for example, open pages, edit something in the admin, create products, etc., your server is loaded from WordPress. If you see a problem with queries to the database, it may be due to a large number of products, filters, attributes or something else. Our theme did not add any tables to your database.
To correctly compare the load with our theme and with the default one, you need to conduct testing under the same conditions. That is, the pages should have the same content: the same menus, the number of items, products and pictures on the page. And you need to perform the same set of actions: the number of pages visited, products added, orders created, etc.
Kind Regards
.
