How is the 90 percentile calculated? Say I am having total
2000 transactions pumped to the system and I have 1800
passed and 200 failed. So the 90 pertile is considered from
the Passed transactions or (passed+failed) transactions?

90the percentile means the highest response time among the
best passed 90% of the attempts of the transaction. In your
example, the transction is passed for 1800 times. So 90% of
1800 values would be 1620 i.e. LR will take 1620 best
response times for that transaction and will report highest
among those. This in turn means (90 percentile means) 90%
of the response times are less than or equal to this
particular number.

90th percentile means 90%of all samples for particular
transaction performing at certain amount of time. If 90th%
is 10sec then 90% of that samples in the load test is 10
sec or less than of it.
U have 1800 passed transactions then arrange transactions
response time in ascending order, consider the response
time at 1620 sample becoz u need 90th percentile
(1800*90/100=1620).
(or) We have formula in excel percentile(n1...nn).
n1= passed samples for particular transaction

Answer / suranjali gupta
90th percentile=0.9*(total transactions i.e passed+failed
