A trivial performance optimisation to help speed up third-party or other-origin requests is to preconnect them: hint that the browser should preemptively open a full connection ( DNS , TCP , TLS ) to the origin in question, for example: In the right circumstances, this simple, single line of HTML can make pages hundreds of milliseconds faster !

The simplest definition of a log record: it describes a single change to a database. An example of this is updating a fixed-width column in a single row—it will do the following: Perform the update, which generates one log record. It can be fascinating to spelunk around in the log to see what SQL Server is doing for some operations.
