Today I was adding the think time between various webpage requests in Jmeter so had to choose a particular timer. At this stage it would be handy to have a picture of the three main types of delay based timers. Therefore, I set about creating one, using the test plan below I had all 3 timer called by the thread. For the Gaussian and Poisson timers I set the mean delay time to 100ms (no offset) and for the uniform I set the maximum to 100 and the offset to 50.
I then ran the thread for 30,000 iteration just to make sure I had a good sample of results and plotted the results.
Now, I have a pretty picture of Jmeter timers to help me choose which best fits how users delay between requests.
