Documentation says -
Can you please explain this using an example waterfall?
All the default measures are based on busy time. Any reason busy time takes precedence over avg duration? I am trying to find the best way to find third party calls which cause issues on site.

Zhu - Can you please explain with respect to the parallel downloads too ? say I have 3 resources being downloaded parallelly and each take 1 2 and 3 seconds respectively.
Hi Jibi,
Please take a look at User Action Timings.
The timings average/min/max that you reference are not splitted by resource. The min is the fastest busy time of all user actions with in 10 sec/1min/1hour/1day depending on the measure aging settings.
Cheers Klaus

Hi,
I am a developer from UEM team.
From the code side, the busy time equals the total duration that resources(either all resources or one kind of resource) on this domain take. If there is only one resource, the busy time is the time that one resource is loading. If there are two resources, the busy time is sum of two resources loading time. And the average duration in this case is the total duration/2.
If you look at the User Action PurePaths, In the purepath tree, there is a timeline column. The busy time(The total duration) of third party resources is also shown as the timeline. And the 'Exec Total' column is also busy time (Total duration). If you right click any third party resource, more details will show up with average/min/max duration for all resources type.
The reason that we set 'busy time' as the default in the thirdparty measures is: from the same third party domain, it probably will loads multiple resources. We would like to show that how much time all the resources loading take. For example, from facebook, it probably loads 2 scripts, 1 images, 3 css. The busy time will give us the total duration of loading those 6 resources. If you choose 'busy time' and only 'script', then the 'busy time' will be the total duration of loading the 2 scripts.
If you would like to find which third party resource is very slow, you can create a measure that has the Longest duration.
I hope this is helpful. If you have any questions, please let me know.
Thanks,
Zhu
