I need some information regarding the output generated after load testing. I have tested load for 100 VUs so what does the following mean: Median(s), 90%(s), 95%(s), 99%(s), Max(s) and Std Dev.. Also, Is the Avg(s) what we get is average of 100 users response timing ?

The description of these performance parameters is provided below: 90% (s)  The maximum response time after excluding the slowest 10% of page iterations  95% (s)  The maximum response time after excluding the slowest 5% of page iterations  99% (s)  The maximum response time after excluding the slowest 1% of page iterations  Max. (s)  The maximum response time  STD  The response time standard deviation is a statistical metrics that helps to find the story behind the data. Here are some references about STD: http://www.robertniles.com/stats/stdev.shtml http://en.wikipedia.org/wiki/Standard_deviation  A complete description of the performance metrics on the page details report is provided here http://support.stresstimulus.com/display/doc46/Page+Details The Avg(s) is, as you correctly noted, the average of all users response times.
