I'am having big performance issues on my actual ecommerce website when I surf between categories of products ( 20 seconds for page loading ) . While my provider is telling me that everything is fine , I start to do some tunning insights :

Activating "page parse time" I see : Parse Time: 14.586 - Number of Queries: 2380 - Query Time: 14.114721213 on pages
That's mean 2380 queries on database for one session in order to display 20 products on a page ? It's a big number , don't you think ?

I really don't know how to solve this ... where to start . I'm asking you some help .
