Queries per second

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

"Query rate" redirects here. Not to be confused with Query throughput.

High-traffic systems must be mindful of QPS to know when to scale to handle greater load.
