jmeter，模拟线程数较少的用户

Question

I am looking for a way to simulate more concurrent users of a web application than I use real threads in jmeter. I want to simulate close to real-world usage pattern, ie user periodically does something on the page but stays logged in 9 hours a day, then logs out. Users in other areas do same at different times, etc. I want to potentially simulate 100000 or even more users of the system. So it makes a big difference if I can use less threads than simulated users. I'll be perhaps using whatever number of amazon ec2 large instances it takes. I can't see any indication that this is possible with jmeter. I guess it is if I write my own sampler and use my own thread pool and save state of each logged in user to some cache but that removes a lot of benefits using the framework.

In a mailing list thread I'm reading some rational but it boils down to being too hard to implement and not worth. Well I think the only real way to test a web app is to simulate the anticipated real usage pattern which means a lot of idle users. So I'm wondering if I'm missing some way to do that or does just nobody care enough to implement?

Try building your own JMeter Cloud using docker & any cloud provider (a lightweight virtualisation). Check my presentation here - http://goo.gl/fJByCb
