The issue, hits sluggish redirect earlier than cached web page making it appear sluggish.
When choosing what to order the merchandise by one thing provides &paged=1 to the url which allways get redirected. It is a drawback as a result of this redirection takes as much as 7(!) seconds the primary time(within the screenshot it hits disk cache) after which hundreds the cached web page. 
However as I do know we by no means need to go to /produkter/?orderby=date&paged=1 I feel I ought to have the ability to filter it from the URL indirectly.
Had the identical drawback when going to the primary web page with pagination, however there I might add a filter to paginate_links, just like this reply. However can I do one thing similiar for the woocommerce-ordering dropdown?
