As Grant repeatedly points out, many who use common table expressions in T-SQL think that SQL Server persists the inner query result set, and that the reason for this belief is the use of the term table in the construct's name.

Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). This is one of the main reasons why content delivery networks (CDNs) exist: They place servers physically closer to the end user in order to reduce latency, and thus delay, as much as possible. and prior (a)).
