keep in mind the average response time is not a true representation. The actual throughput might be more useful in this case. Most likely the response time are varying dramatically, which causes the average to be higher than what you expect. In the nightly build, there's a new distribution graph I just added last week. this may give you a better picture of what is happening. In the past I've seen this happen when the dataset clumps at opposite ends of min/max response times. Even though 50% of the requests may be finishing within 100ms, the average can be skewed if 20% of the response times are un-usually long. I hope that helps. peter
Ivan Rancati <[EMAIL PROTECTED]> wrote: good morning, I have some beginner doubts on how exactly to read measurements for a simple Fast CGI website (or perhaps I don't understand how to use loops), and I did not find an exact answer on the documentation. My test plan is simple, I have a thread group with 20 threads, no ramp up time, loop 15 times then Interleave controller (ignore sub-controller blocks is selected) HTTP request 1 HTTP request 2 HTTP request 3 HTTP request 4 View Results in table View results in tree Aggregate report the 4 http requests go to FastCGI pages that have very similar execution times, and for each page I have a simple Response Assertion (same for all 4 pages) At the end of the run, View results in Table gives me an average of 1884 ms for the 300 samples. Aggregate Report gives me a thoughput rate between 2.2/sec and 2.8/sec for each of the 4 http requests, and a total rate of 10.1/sec. Now, if 10.1 total requests are processed in a second, and I have 20 threads, where does the average sample time of 1884 ms come from? I would expect something like 99 ms (since throughput is 10.1 requests in a second), or 1980, which is 99 ms times 20 (the number of threads) Also, occasionally, in View Results in Table, I see a sample time of 0 ms, which looks odd. I am running JMeter 2.0.1 on German Windows 2000 (with latest service packs) and JVM 1.4.2_04. The server is a Linux box with Apache and Fast CGI Apologies if this is already covered in some faq or in the docs, I could not find it. thanks and best regards, Ivan Rancati QA engineer - SharpMind.de --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------- Do you Yahoo!?
