1. Concurrent number

Number of registered users: all registered users

Number of online users: online users, but not necessarily interacting with the server

Number of concurrent users: online users who must interact with the server. In LoadRunner, it refers to the number of virtual users and the number of threads in JMeter.

two。 Business

Transaction

3. TPS (Transaction per secon)

Transactions per second-I think it's the most important measure of performance.

The larger the TPS, the better, indicating that the server has more processing power.

It is based on transaction statistics, so transactions must be defined first.

TPS is not equal to Throughput. Statistics at different latitudes.

From a network point of view, throughput is the amount of data transmitted on the network per unit time.

Throughput = throughput * unit time

4. Response time (RT)

As shown in the figure above, if the response time is long, it should be consumed in two places:

First, on the network: N1 N2 N3 N4

Second, application: web server, database server

There should be a third point: the display time of the front-end page.

5. Thinking time

If the actual user request is simulated, then think time is added.

Performance testing is generally pressurized as much as possible to test the bearing capacity of the system, so generally without thinking time.

If you add thinking time, compared with not adding, it will bear more concurrency, and the test results have a great impact.

6. PV & UV

Page view: page views or clicks are counted each time the user refreshes. It can be considered that a refresh by the user causes a request to the server.

Unique visitor: the client of a computer that visits the website is a visitor. The same client is counted only once between 0 and 24:00.

7. Resource utilization ratio

It generally refers to CPU, MEM, etc.

8. Click rate

The number of http requests submitted to the server per second.
