Starting process, worker use too much cpu resource. Starting many processes sometime cause agent lost or other problems.

  2. Run agent on windows 10

  3. Run test

  4. In Task Manager, CPU usage is 100% for every ramp up.

@kdw9502

In the process of creating a new worker processes for testing, you can use a lot of CPU for a little while.
Did you actually have some problem like agent loss or other in preparing phase?

  1. How many CPU cores do you have?
  2. Do your script do some job in @BeforeThread (sth like loading files?)

I found that some problems only occrus with python script test, not due to cpu usage.
