WooCommerce: WP Rocket's "clean" functions run numerous times during checkout

[vmanthos]

On WooCommerce sites, when:

• items are added in the cart,
• User Cache is enabled and
• a "native" payment gateway is used, i.e. one that uses WooCommerce's stock update functions,

WP Rocket's rocket_clean_post() and rocket_clean_files_users() are called numerous times, proportional to the items that were added in the cart.

If those are just a few, everything is working as expected. However, when a lot of items are added in the cart, this can lead to the script timing out and the order taking a lot of time to be processed and completed.

For the rocket_clean_files_users(), we could limit it to run just once per order.

I'm the guy who reported the issue by Camila. Happy to help test and see if there's a solution. I love WP Rocket but our best customers, the ones who make big orders, have an awful experience because of this. Thanks for your help!

As a possible solution, we could disable the automatic cache clearing/preloading until after an order has been processed.

We would need to store the IDs of the products for which we need to clear cache/preload.

Any update ? What i found on my website is that checkout is vary slow (30+sec) if the products belongs to multiple categories.
