I noticed quite long waiting times for the list view to contracts (account.analytic.account) having many tasks open for invoicing.
What is the best way to deal with this. I check PostgreSQL activity - but there are no bad queries. Everything is in Odoo in "function fields" or in the ORM-Layer.
For now I found a quick solution: I just gave my own user the right "Analytic Accounting" and then I found the menu: Accounting/Configuration/Analytic Accounting/Analytic Accounts
--> This list-view is perfectly fast since it doesn't sum up all open tasks.
