The content is reproduced, the specific circumstances should also be specific reference, practice can out the truth TPS (Transaction per Second) definition TPS is the abbreviation for transactions per Second, which is the number of transactions per second. It is the unit of measurement for software test results. A transaction is the process by which a client sends a request to the server and the server r

Example: A high-speed road with 10 entrances, each entrance can only be 1 vehicles per second1. How many cars can I get in 1 seconds? tps=102, how long does it take for each car to respond? reponse time = 13, change to 20 cars, how few per second? How long is the response time for each car? TPS = 10,reponse time = 14, ingress expands to 20, how few can I enter per second? How long is the response time fo

[Performance Test] LoadRunner Results Analysis –tpsFor the relationship between throughput rate and TPS, how to use this in the analysis of results, after personal experience and friends to discuss, put forward the following suggestions to guide, welcome the colleague to correct. Related definitions response time = Network response time + Application response time response time = (N1+N2+N3+N4) + (A1+A2+A3) tps:trasaction

PS: The following is the main concept and calculation formula of performance test, note: A System Swallowing metric elements: A system's swallowing metric (pressure-bearing capability) is closely associated with the request's CPU consumption, external interface, IO, and so on. The higher the CPU consumption of a single reqeust, the slower the external system interface and IO impact, the lower the system throughput, and the higher the converse. System throughput Several important parameters: QPS

This paper compares two kinds of calculation methods on the Internet. Let's take a look at the relevant concepts. Concept: Qps:queries per Second Query Volume/sec, is a server per second can be the corresponding number of queries, is a specific query server in the specified time the amount of

Author: gnuhpcSource: http://www.cnblogs.com/gnuhpc/ TPS: the number of transactions processed by the transaction per second server per second. Transactions per second (number of transactions processed per second), that is, the number of transactions processed by the server per second. It is the unit of measurement for the software test results. A transaction refers to the process in which a client sends a request to the server and then the server r

Reponse time = 1 3, change to 20 cars, can enter several per second. How long is the response time for each car? TPS = 10,reponse time = 1 (10 are first-class, divided into two equal parts, the average

When the pressure of the system is increased (or the number of concurrent users is added), the throughput rate and the change curve of TPS are broadly consistent, the system is basically stable.If the pressure increases, the throughput curve added to a certain extent after the change is slow, even flat, while TPs tends to flat, view system resources utilization, if the resource utilization rate is low, indi

During the demand research phase, we will know the business model of the test system, including the number of transactions, the daily volume of each transaction (PEN/day) or the peak time volume (pen/time), resulting in the total expected TPS and the proportion of each transaction. This is important to configure the scenario based on this ratio in both the mixed stress test scenario and the stability test scenario. So, first of all, how is
