Hi All,

I am working on Design Studio 1.6 SP4. We are facing performance issue with existing dashboard specially when End User opens a dashboard it takes more time to render.

When I did inspection using Chrome browser, I found there a "Zen" xhr file which is taking 20 Sec to load. Once this file is loaded rest of things start loading quickly.

Any idea on what is ZEN XHR file and why it is taking so long time.

Hello - have you also run the profiling/statistics that Karol mentions here: https://blogs.sap.com/2015/06/30/understanding-profiling-and-statistics-in-design-studio/

That should provide some more insight

Hi Tammy,

I am working on 4.1 SP6 environment. In Production we are having 2 BO Web Application Server with configured Apache Load balance and 2 BO Application Server. We have Design Studio 1.6 SP4.

If I am trying to Open a Design Studio dashboard from iPad it is taking 16 seconds to initiate and load, but if am running same dashbord from browser it is taking 30 sec to initiate and load.

When I tried to find out using fiddler on browser multiple JS and CSS files are being called from

https://<Server>/BOE/OpenDocument/1702172327/shared

https://<Server>/BOE/OpenDocument/1702172327/shared/yui

https://<Server>/BOE/OpenDocument/1702172327/shared/js

https://<Server>/BOE/OpenDocument/1702172327/shared/ure

which is consuming most of the initial time.

Regards,

Swapnil

Hi - is your platform sized correctly? It is strange, usually things take longer on the iPad

See this for sizing information:

https://blogs.sap.com/2017/10/11/sizing-for-sap-lumira-2.0-asug-webcast-recap/

Which browser are you using?

Hi Tammy,

We are using IE 11.

Swapnil - my experience is that IE11 will be slower; perhaps try another browser? Chrome?

Hi Tammy,

Thanks a lot for your inputs.

I did executed the dashboard on Chrome as well not major improvement in performance except 1-2 seconds.

But I did a little bit deep analysis of Fiddler and found that there are two calls are being made for "https://boserver/BOE/OpenDocument/1702172327/zenwebclient/zen".

First call is to load components which are static (Labels, Layout, Panel etc) and in sec components with processed data being loaded (scorecard, charts etc.).

These two calls does not allow to store or share Cache memory and consuming 17 seconds overall.

Rest all CSS and JS libaries are consuming 300 mil each approx. But I could see total 30+ CSS+JS files which consuming total 12 Sec more. Though these files are in cache it is consuming more time.

Please let me know if these findings are correct or not.

Regards,

Swapnil

Hi Swapnil

I am facing a similar issue with my application. I have loaded all data source on demand and optimized script to my best knowledge. But this particular resource seems to be taking 7-10 seconds to load thereby increasing the startup significantly. Is there any solution to this? A work around perhaps? or a way to ignore these files?

Hi Maya,

I am still working on this issue. Just came across below discussion today

https://archive.sap.com/discussions/thread/3940727#

Hope it may be useful for you.

Can please try running your application using IP in URL and compare the performance. If you found app with IP URL taking less time most probably its network which is causing the issue.

If performance is same then we can look at other parameters like Components, Data Sources.

Regards,

Swapnil
