The project uses Mina for underlying socket communication, and performance tests are required. LoadRunner is too difficult, jemeter is small, and the functions are complete. Implement jemete tcpsampler by yourself.

 

Summary:

 

1. thread group: indicates a certain number of concurrent users. It can be used to simulate concurrent users to send requests. The actual request content is defined in sampler, Which is contained by the thread group. You can create a thread group in "test plan-> Add-> thread group", and then there are several input columns in the thread group panel: thread count, ramp-up period (in seconds) number of cycles, in which ramp-up period (in seconds) indicates that all threads have been created during this time. If there are 8 threads and ramp-up = 200 seconds, the thread startup interval is 200/8 = 25 seconds. The advantage is that there is no heavy load on the server at the beginning. A thread group is designed to simulate concurrent loads.

2. Sampler
Java request: a self-written Sampler

3. Aggregate reports
Label: Sample name
Samples: the total number of requests sent during the running process. Generally, the value is equal to the number of threads * The number of cycles (prerequisite: The test is completed as planned, with no threads terminated abnormally ), for example, if five threads exist and each thread loops for 10 times, the number of samples in the corresponding row is 5*10 = 50. The total samples is the sum of samples in each request.
Average: average response time
Median: Median in response time
90% line: Response Time: 90% lines
Min: minimum response time
MAX: Maximum response time
Error %: error rate (number of failed requests/number of all requests)
Throughput: throughput, number of requests processed per second/minute (For details, refer to the units following "/")
KB/sec: the amount of data received from the server per second, equivalent to throughput/sec in LoadRunner
[Note] the overall value is not the sum of all columns. Is the statistical value of all samples, such as: Overall min = min {min} of each samples, overall max = max {max} of each Samples}
