In the Sampler result, I don't know why the "Load time" and "Latency" are often over 10000 and sometimes over 20000, but the actual time per request should be 2-4 seconds if run in browser.
My "Thread Properties": Number of Threads (users): 5 Ramp-Up Period (in seconds): 0 Loop Count: 1 If "Load time" is divided by "Number of Threads", then I think the result is reasonable.
