I have magento 2.4.5 and my own dedicated server with elastic search installed. my catalogue page takes forever to load (16 sec). I have 18K products.

Magento profiler shows me:

TEMPLATE:/var/www/magento2/app/design/frontend/mytheme/mytheme/Magento_Catalog/templates/product/list/toolbar.phtml. with a 14.405653s time · EAV:load_collection 0.679354 · load_entities 0.571876 · set_orig_data 0.010517 · after_load 0.096795 

There is nothing in mysql slowlog, I reindexed everything again, I have varnish installed.

What I am missing and what is the next step?
