public class AverageSystemLoadServlet
extends jakarta.servlet.http.HttpServlet

AverageSystemLoadServlet is used for stressing the server's CPU.

Usage:

You may GET e.g. this URL: http://localhost:8080/clusterbench/averagesystemload?milliseconds=20000&threads=4 By doing so, there will be 4 threads with evil active-loops created. These threads will be running for 20000 milliseconds.

After the aforementioned time, you shall receive a response saying something like:

DONE, I was stressing CPU with 4 evil threads for 20000 milliseconds (including warm-up).

NOTE: Do not forget to set some reasonable time-out on your client... That's it. No more functionality.
