Queries per second (QPS) is a metric used in online systems to measure the number of requests for information that a server receives per second. It is a critical parameter in evaluating the performance and capacity of information retrieval systems, such as search engines and databases. In the context of digital advertising, a high QPS measure is desirable as it indicates that the ad network or exchange has sufficient capacity to handle a high volume of requests.
Calculating QPS is a straightforward process. If you already know the number of queries that your system processes per second, you can use the following formula to determine your QPS rate:
QPS = (number of queries per second) x 60 seconds per minute x 60 minutes per hour x 24 hours per day x 30.41 average days per month.
By applying this formula, you can determine your system’s average monthly query total. It is essential to monitor QPS regularly to ensure that your information retrieval system can handle the expected level of traffic without affecting performance or causing system failures.
