Can anyone explain me about the above columns how exactly are they getting calculated (50th pct,75th pct,99th pct,Std Dev) for both global information and each requests individually.

Yes Flavio,First of all thank you for replying…the link which you shared is helpful

But can u confirm what i have understood after going through the link is right or not…In the above case of results screenshot, out of 1243305 requests being sent…at 50th percentile ie…,completion of half requests(lets say around 6L requests) the response times for those completed half requests fall under less than 159ms bucket and the same applies for 75th, 95th and 99th…

Corerct me if i am wrong
