For each request, it counts the response information and provides the number of requests, average, maximum, minimum, error rate, approximate throughput (in Requests/sec), and throughput in kb/seconds.
The throughput is counted from the point of view of the sampled target (for example, the remote server set in the HTTP request sample). JMeter will take into account the total response time of the generated request, so if there are other samplers or timers in

This paper mainly introduces the usage of common tools jmeter in performance testing, so as to make it easy for the developers to self-test the system and simulate the user operation access request. Finally, a simple comparison is made with the pressure measurement tool ab under Linux.1. Introduction to JMeter Related concepts:JMeter is a Java-based stress testing tool deve

2. the MD5 value must be added before the HTTP request (which belongs to the Jmeter Preprocessor range ).
Ii. Problems to be Solved
1. Get and add parameters in the HTTP request of Jmeter
2. Implement the specific MD5 Logic
3. append the generated MD5 check value to the HTTP request parameters at the appropriate time.
4. integrate it into the Jmeter menu for ease of use.
3. Solution steps
1. Because you have no Jmeter plug-in development experience before, you need to learn how to develop it

These two things can be considered as special type variables. Texture is the mapping resource used in shader, I think there is nothing to say. To explain the sampler: in fact, each map should use a
order to create a load test in jmeter, you need to build a test plan. In practice, JMeter needs to perform a series of operations. The simplest test plan typically includes the following components:* Thread groups-these components are used to specify the number of threads to run and the wait period. Each thread impersonates one user, while the wait period is used to specify when all threads are created. For example, the number of threads is 5, the wait time is 10 seconds, and the interval betwe
