Long response time in User Action Purepath
Hi,
I have a user action purepath of 119132ms but when click on the details I only see about 1000ms of duration (see image). Where should I look to find out where the rest of the time is taking place.
The main reason I ask is that I can see lots of very small jpgs taking over 30 seconds (shown in the purepath response), we have Amazon cloudfront , load balancers and shared storage which could all be causing the issue. The purepath always say "IO" so it looks to be waiting somewhere but everytime I load the image it comes through quickly.

Thanks, Raffaele

Is this what you are after?

Hi Paul,
Yes, that's perfect !
I think the answer here lies in the definition of the "onLoad Handler", it shows the time spent in activities after the page is loaded. So here, you'd have the loading of the page, then the onLoad would start working on other things.
If you look at the detail in the session you sent me, you'll see 86 seconds are spent for processing, that is already a lot:
Then, when looking at the tree you'll see this:
What you see here is you have a total time of 305 298 ms, this time contains the 224 652ms on the onLoad Handler, that started 80 646ms after the load of the page, and that is why you get such a high response time.
Does this help ?
Pierrick, thankyou. So this is being cause by the client, in this case an Iphone taking a long time to process the page? If this were a desktop is Dynatrace able to show that all simultaneous connections were full?
Paul
Paul,
I have trouble understanding "full connections", can you explain what you mean ?
In any case, yes it is on the client side, you can see it in a more obvious way using the Transaction flow:
You see 5mn are spent on the mobile device (here an Iphone).
Thats fantastic, thanks.
So our pages have lots of images on and a browser can only download a numebr of files at any one time. I am thinking that certain browsers may be slower than others due the the number of simultaneous connections it can make to the server.
I will do some more testing my end.
Thanks again.
Paul
No problem, let me know if you need anything else, if not do not forget to mark this as resolved by accepting answer.
Cheers,
If only I could figure that out, I will gladly accept the answer. I can only see the option to close.

Hi,
It would be interesting to see the detail int he Web Request with the code 200.
Here what you need to consider is the Elapsed Time which the time between the start of the Purepath and the Entry of the method. Showing th entire Tree will help you identify where the 10 seconds happened.
If you can send a session that'd be great,
Cheers,
Pierrick, where can I send the DTS to? They are too big (1.2MB) to upload.
This is another example with "Expand All" selected.
Hi Paul,
You can send it to pierrick.planchon@dynatrace.com,
Also if you can provide the screenshot mentioned in Raffaele's comment, that'd be great.
Thanks,
Lol, I can see lots of "Accepts" now!
