When first starting a database I get very high USER IO: I used db optimizer to see what stands out. user 'Unknown', is shown to be consuming IO - it is connected to Non-SQL Activity with an SQL_ID of 0, and a SQL_ID which is connected to the Advanced queuing wait event in the subject line. I am unsure how this wait event or session is connected to the IO. Has anyone come across this before? Don't use AQ purposely in this DB or others.
