Hi Richie,
Thank you for your query.
It is good that you have caching on your site, But that has nothing to do with how fast your site is capable of adding products to cart. Caching is specifically disabled during the add to cart process, so it doesn’t help there. A site could be loading in 1 second with cache and still have a slow add to cart speed.
So we need to first find out if the issue is related to WooCommerce Product Table or if your site is in general slow at adding products to cart.
For this, you can run a simply test. Just try going to the any product page on your site and try adding the product to cart using its woocommerce add to cart form. Note the amount of time it takes to add the product to cart from its own page and then compare it with how long it takes to add the product to cart from a WCPT product table. If you find that the product is being added to cart quickly from its own page whereas its taking a long time via the table, then we know the issue is in some way related to WCPT and we can look further into that.
I tried running this test on your site but I found that your single product pages are disabled for site visitors. Perhaps you are still able to access them as the site admin and can run this test at your end.
I did notice another relevant thing on your site. When I add a product to cart, then go to the cart page, and try changing the cart quantity for the product and click on ‘update cart’ – the cart update takes a long time to complete. This indicates an issue on the site in general with adding products to cart quickly. But you will have to check the single product page to be sure.
Normally WCPT takes about the same amount of time to add products to cart as the add to cart form on the product page. If this is not happening, then chances are that WCPT is facing a conflict with another module on your site.
In such a case to find out which module is conflicting, you can go to the WCPT support page and follow the ‘Debugging Steps’ guide.
Please let me know if you have any further questions.
Regards,
Kartik
