Hey Felix Namaskara~Nalama~Guten Tag
I did try your scenario with Webload (www.webload.org) and it worked fine. It could crash the webserver. I am unsure why Jmeter is waiting. Is your application response time increasing so much, that no mater how much you increase the threads, nothing happens. This option should work in all probability. > Or is all of this complicated setup == a >> large thread group + long ramp up period?
