![]() How 90 th percentile calculated in MS Excel? It means 90% of total iterations have a response time of 1.9 seconds or less than it. Similarly, you can calculate other percentile values like the 70th, 80th or 95th percentile. So the 23 rd value will be the 90th percentile which is 1.9 seconds. Now, 22.5 is 90% of the number of transactions i.e. Now, sort the list in increasing order with respect to response time. The response time of the login transaction of each iteration is: S. Example:Ī performance test script is executed for 25 iterations. The last highest number in the remaining values will be the 90 th percentile. ![]() In terms of performance testing, you need to sort the response time of a particular transaction or request in increasing order and then ignore 10% of the total count having high values. The conclusion is 90% of total sheep either eat 4 KGs grass or below, so you got an upper limit of grass consumption. The 90 th percentile value in 10 entries is a 9 th value which is 4, so just ignore S4 with 4.8 (keep it hungry for some days, it eats so much). So simply you need to sort the number with respect to consumed grass and ignore the last value. Now, you need to find out what amount of grass has been consumed by 90% of sheep. One day you weighed the grass and noted the figures of each sheep’s intake. If you had 10 sheep and each sheep eat some KGs of grass on a daily basis. So, what is this 90th percentile exactly? ![]() Even our mentor gave more stress on the 90th percentile figures for response time. From the day first when we started analysing any performance testing report, we heard about the 90th percentile. ‘Percentile’ – a common but most important term, especially in performance testing.
