Hello,
In general, our theme is already optimized and doesn’t have too many resources to make your website slow. Most likely, your website performance suffers from the content you have added to your website. It may happen in case of too many plugins, large not optimized images or other resources.
Products are controlled by WooCommerce and our theme doesn’t influence this. You can have as many products as you require on your website.
