Performance testing index is mainly composed of the following indicators:
-
Transaction:
- One or more requests (requests which form a complete operation) initiated by the client to the client receives a response returned from the server
-
TPS ：
- Number of transactions per second can be processed by the system (not necessarily a request)
-
Request response:
- Starting from a request initiated by the client, the client receives a response back from the server, the process time consumed
-
Transaction Response Time:
- Transaction may be composed of one or more requests, the transaction response time is primarily for users, such as: Transfer
-
Concurrency:
- Definition: no concurrency in the strict sense, there has always concurrent, whether the gap is 1 millisecond or microsecond, there is always a time lag, so the concurrent tells of a time frame, such as one second
- Concurrent example:
- Multi-user operating on the same system, for example: when two-eleven, we have carried out for the same commodity spike
- Multi-user operating on different systems, such as: When two-eleven, we carried out for different commodities spike, or we have carried out various other operations, such as browsing merchandise
- The same time the number of users on the system initiates a request: The number of concurrent users
-
Throughput:
- The sum of the amount of data transmitted during a performance test of the network
- There is a proportional relationship with the size of the bandwidth
-
Throughput:
- The amount of data transmitted on the network per unit time
- Throughput = throughput / transmission time
-
Hits:
- The number of requests per user submitted to the server, this ratio is an indicator web application-specific, it is conceivable, for how many clicks per user for a total on the page, but it should be noted that a single mouse click after the operation, the client may send multiple requests to the server
-
Resource Utilization:
- Use of different system resources, such as: CPU, memory, IO
