Aha, I think I know this.... In addition to the 'normal load' thread group, add a second 'surge load' thread group to the JMX with a short ramp and high number of threads. In this new thread group, the first sampler is a Java sampler set to sleep 'x' seconds. After that initial delay has passed, the 'surge' kicks in. However, if you iterate this thread group, just note the sleep delay precedes each surge.

I'd like to be able to simulate a sudden spike or burst of requests against the webserver I'm load testing. At the moment I have two machines doing it, so midway through a run I'll hit the server from another machine with a seperate instance of jmeter running on it. Is there a more elegant way of doing this i.e. after 1000 samples the load spikes to 100 threads looped 5 times with a very short ramp up, before returning to "normal" load levels? Any help would be appreciated.
