AkshayPanda Imported 300 products by CSV into a client shop on Friday. Since then the shop page loads in about 8 seconds. Single product pages still load in under 2. Classic theme, Hostinger shared, Woo 11.0. Where do I even start looking?
Atif Query Monitor first, because 300 products is nothing for Woo and 8 seconds on one page means something runs per product or per term there. https://wordpress.org/plugins/query-monitor/ load the shop page logged in: open Queries by Component and sort by time so the slowest query and the plugin behind it sit on top. Fine product pages point at the archive not the import.
Mattia Had it on a client shop, a filter plugin counting products per term on every load. Took twenty minutes in Query Monitor. Same symptom. Thank you.
