If you PREPARE a query you can assign it a name which will then be logged.
If a query does not have a name you end up seeing <unnamed> where the name
would go.
You indeed have issues if simple query parsing is taking 3.5 seconds...
I don't know the specifics of how these are measured and you provided
insufficient information for anyone to hazard even a guess.
