Common terms in LoadRunner
With regard to performance testing, we often hear terms such as maximum number of concurrent connections, maximum new connections, throughput, and so on. If you come into contact with these concepts for the first time, these concepts are easy to be confused. Let's talk about it briefly below for personal understanding.
Maximum number of concurrent connections
Refers to the maximum number of simultaneous connections established between the client and the server. In the LR scene resources, the Connections graph is used to find the stable value.
Maximum number of new connections
It refers to the maximum number of new connections per unit time between the client and the server, which is similar to the maximum concurrency. It both refers to the number of connections between the client and the server, but the maximum concurrency emphasizes maintaining at the same time. The maximum new construction, which emphasizes the maximum new construction per unit time.
In the LR scene resources, Connections per Second graph to find the peak of the graph.
Throughput
The sum of the amount of data transmitted on the network during a performance test. Throughput / transmission time is throughput.
LR scene resources, Throughput graph.
Throughput rate
It is usually used to refer to the amount of data transmitted on the network per unit time, or it can also refer to the number of client requests processed per unit time. It is an important index to measure network performance.
TPS (Transaction Per Second)
The number of transactions or transactions that the system can handle per second. It is an important index to measure the processing ability of the system. TPS is an important performance parameter in LR.
