The new version 2.2 of the WOOF by Category plugin, whose number of active installations exceeded one thousand, has a significant improvement in performance.
On client sites with a long list of product categories, there was a significant slowdown in the generation of WooCommerce pages with WOOF filters. The reason is that the WOOF plugin requests its options hundreds of times during page generation. These calls are handled by WOOF by Category to ensure its functionality.
On the site with 2,000 products and 70 categories option was requested 800 times during the generation of the page. The caching used in version 2.2 reduced the number of executions of the main WOOF by Category function to one, and the page generation time on the above site was reduced from 4.5 to 1.5 seconds.
