Bit confused here. Is the SQL faster or the view?

Anyways, using a view also reads from the database. If the database is on the network, it is expected that reading from the view is slower. But there is more to it. If you specify a database(!) prefix in the from clause it is reading more from the network than when reading from an already open alias.
