Queries per second

Queries per second (QPS) is a common measure of the amount of search traffic an information retrieval system, such as a search engine or a database, receives during one second.[1] The term is used more broadly for any request–response system, more correctly called requests per second (RPS).

"Query rate" redirects here. It is not to be confused with Query throughput.

High-traffic systems must watch their QPS in order to know when to scale the system to handle more load.
