1. ## Min,Avg,Max

Hi All,

I have run a scenario in Loadrunner Controller.
In the analysis part i find various Transaction times for a transaction for MINIMUM,AVERAGE,MAXIMUM.

I want to know what these signify and what they mean.

with regards,
sathakarni.

Minimum - The least amount of time in seconds taken to do the transaction

Maximum - Tbe most amount of time to do the transaction

Average - The average amount of time to do the transaction.

Thank you very much Matt.

In my experience, the most accurate view of response times is using the analysis tool, creating an html report, and then using the 90th percentile column.

Eric,

I am new, So can you throw some light on what you have posted.

The 90th percentile column is useful because it removes any large anomaly data that can skew your results.
Standard deviation gives you a feel for the spread of data, but is not as immedietely intuitive and requres knowledge of statistics. Check out some resources on statistics to get a deeper understanding.

I would suggest that Average is more realistic than 90th percentile when volumes of vusers and iterations are low.

Given that it will only take 11 percent of anomalous data to skew the 90th percentile, I only use that when there are plenty of users & iterations to balance it out.

8. ## Re: Min,Avg,Max

Matt by that logic, any anomalous data will skew Average!

I am just championing the fact that 90% CAN give you cleaner results, all things being considered. It is also useful as a lot of service level agreements do define a percentage user threshold

i.e. "90% users submit transaction in 5 seconds or less"

The 90% figure can change, but this is configurable in LoadRunner as well.

I also use Average, but only if the data allows it to be used - i.e. the spread of results does not detract from the actual results.

Sathakarni - I agree with Baz's assessment of the 90th percentile. Average is skewed because of anomalous data. However, if your standard deviation is small, average and 90th percentile will be close. Good luck!

Hi-All, Thanks for the input for me, and i am working on it,let you know after i finish about it.
