what do you mean by 90 percentile in the Lr report..

Answer / raja

The 90th percentile tells you the value for which 90% of
the data points are smaller and 10% are bigger.
Statistically, to calculate the 90th percentile value:
1. Sort the transaction instances by their value.
2. Remove the top 10% instances.
3. The highest value left is the 90th percentile.

Example:
There are ten instances of transaction "t1" with the values
1,3,2,4,5,20,7,8,9,6 (in sec).
1. Sort by value -- 1,2,3,4,5,6,7,8,9,20.
2. Remove top 10 % -- remove the value "20."
3. The highest value left is the 90th percentile -- 9 is
the 90th percentile value.

Answer / sivaramaraju

if you arrange the 100 response times from good to bad i.e
in ascending order.the 90 percentile response time is the
90th response time.so if 90th response time is in the
acceptable range since the elements are in ascending order
we can say 90 out of 100 response times are in the
acceptable range other 10 might be in the acceptable range
or may not.

4 user 04
5 user 12
6 user 15
