Load generator CPU is reaching 100 percent

venu.sss Posts: 1 10/20/2023	venu.sss Posts: 1 We are running load test with 1000vu in our project. We used 4 load generators. CPU on LG machines is going to 100% when the user load reaches ~150 on Load generator. I have verified the LGs before starting the test. CPU on all machines is less than 3 percent. During the test, only Stresstimulus process is taking ~98 percent cpu.

Here are a few suggestions you can try: Make sure you configured a realistic think-time (https://support.stresstimulus.com/display/doc58/Think+Time). It typically should be what It takes for an average user to look at a page and make their next click. Selecting a too-low think-time can cause inaccurate performance test results. Make sure you have enabled the client execution delays, representing client-side page rendering time and script execution time (https://support.stresstimulus.com/display/doc58/Client+execution+delays) If you have multiple test cases, one of them may use CPU cycles the most. You may execute your test with various combinations of the test cases to single out a test case causing high CPU utilization and troubleshoot it separately. For more targeted troubleshooting, additional details would required that you can discuss with your support rep. - Cheers
