90 Percentile line in JMeter Aggregate Report
Rohan Sakhale 11/21/2016 jmeterreporting
The 90% percentile line is where the response time fall under the smallest range of 90% and rest 10% are considered as higher values which are ignored.
# Calculate
- Sort your transactions by response time
- Remove 10% highest time taking transaction
- Now the transactions left are your 90 percentile values.
# Example
Lets consider we fire 10 threads for a transaction which gives us values as below
Transaction A > 3seconds
Transaction A > 4seconds
Transaction A > 7seconds
Transaction A > 2seconds
Transaction A > 9seconds
Transaction A > 1seconds
Transaction A > 5seconds
Transaction A > 8seconds
Transaction A > 10seconds
Transaction A > 6seconds

Now after sorting the above transaction we get as below
Transaction A > 1 seconds
Transaction A > 2 seconds
Transaction A > 3 seconds
Transaction A > 4 seconds
Transaction A > 5 seconds
Transaction A > 6 seconds
Transaction A > 7 seconds
Transaction A > 8 seconds
Transaction A > 9 seconds
Transaction A > 10 seconds

Now removing the highest 10% value will pop out transaction with 10 seconds
Transaction A > 1 seconds
Transaction A > 2 seconds
Transaction A > 3 seconds
Transaction A > 4 seconds
Transaction A > 5 seconds
Transaction A > 6 seconds
Transaction A > 7 seconds
Transaction A > 8 seconds
Transaction A > 9 seconds

Now the highest value left out is your 90th percentile value as 9 seconds
