Hi all,
I'm new to JMeter and ran several tests against our website over the weekend using HTTP. We configured our tests to use a CSV file to populate variables within our test and ran our test starting with a thread count of 25 users and slowly increased the number of threads until we reached 2,000. Our ramp up time was 4 seconds, which according to the documentation looked like we would have divided the ramp up time by the number of users, i.e., 4 secs/100 users would have mean 25 users per second. I realize that it probably wasn't realistic to think 1,000 users/http requests could be initiated in 4 seconds, but how does JMeter determine how many users to launch simultaneously? My goal was to attempt to break our system by finding the number of users at which point our server would crash. Instead, the more threads I used, the longer the total script took to run. This doesn't seem to correspond to the JMeter docs for the ramp up time. Any help would be appreciated. Trebor
