Preface
The tepping Thread Group is the first custom thread group. However, with the iteration of the version, a better thread group has replaced the Stepping Thread Group [Concurrency Thread Group], so the Stepping Thread Group is already a thing of the past, but it is still introduce
Features of Stepping Thread Group
- There is a preview showing the estimated load;
- Thread groups can be started lazily;
- Continuously increase thread load;
- The continuous running time of the maximum load can be set
The role of Stepping Thread Group
- To reduce the instantaneous pressure on the server, performance testing should gradually increase the pressure rather than instantaneously;
- The smoother the gradual pressure increase, the better. It is easier to see from the results at what pressure value there is a performance bottleneck.
Detailed explanation of parameters
Understand all parameters from the load preview image
- Start threads from 0 seconds, start 10 threads every 5 seconds and run for 30 seconds, and cycle until a total of 100 threads are started.
- After 100 threads have been started, the load runs continuously for 60 seconds
- After continuous load operation for 60 seconds, five threads will be released every 1 second until all threads are released [Note: During the thread release process, the threads are still running]
Combined with Active Threads Over Time
– Running Stepping Thread Group needs to be combined with Active Threads Over Time, so that you can see the dynamic step pressure effect; you can see that it is basically the same as the Stepping Thread Group load preview, proving that the pressure effect is normal.
