If you have a large number of calculations or conditions, you might find that page performance is affected. If you find that the product page has slowed or is unresponsive, you can enable a couple of options.
Go to WooCommerce > Settings > Products Add-Ons and enable:
- Optimise calculations
- Optimise conditions
Note that these options are still in beta so you should test your product page to ensure that it’s functioning correctly.
