Do you have a premier support contract in place? If so, they should help you here quite fast
Sadly not yet. But this case that we need some sort of premier support.
We've had poor performance recently, so we opened a ticket with Microsoft Premier Support. They were able to track down a few of our sites/pages that were putting a heavy load on the SharePoint/SQL servers. Microsoft did some changes on their servers and we're making changes to our pages.
One of our tasks is to optimize the views on a large list (60000+ items).
On another page, we have list web parts that are doing audience targeting based on a managed metadata column (causing excessive SQL queries).
