We are facing issue with WooCommerce. We have as of now 30000+ Categories on our website.(In the future we may have upto 70000+ Products->Category) For every product we have one category and those categories has parent category. So, we have custom taxonomy plugin where you could see all the categories listed. If we click a category which has for instance (1500+) above products. Then website hangs and it won’t display the products listing page. Can you help us with the solution?

Note: On the right hand side of my website beside slider you can see taxonomy section. Here instead of products we are displaying species.

Looking forward to your response.

Regards

San
