HTML VIEWER Performance issues

[matthias_langer]

Hi,

We developed for a customer a report using HTML control in SAP GUI for Windows.

Since the customer upgraded from SAP GUI Version 7.30 to 7400.2.7.1112 he experiences tremendous performance issues related to the HTML control. It takes up to 25 seconds till the HTML refreshes.

When debugging the code there is no command that consumes the time. Normal GUI input fields are ready for input after any action triggered, but the HTML is not updated for a very long time.

Did anyone experience the same problem and could suppose a solution?

Thanks for your help.

Best regards

Matthias

Hallo Matthias,

I would suggest first, that you install the most recent gui patch 9

Does the issue depend on browser versions?

Try capturing a performance trace from the gui (ALT+F12 -> Traces -> "Session Traces" check "performance" and "Automation", then recreate the issue and upload the results here.

Regards

Jude.

Hi Jude,

thanks for your help.

Sap Gui Version:

7400.3.9.1125

Build 1676784

Patch level 9

I attached the trace file.

(it took about 14 seconds to show the first screen with the html container)

I did not change any browser version up till now. I use Chrome as standard browser. (Version 51.0.2704.103 m (64-bit))

IE is also installed. (Version 11.0.9600.18378CO; Update version 11.0.33)

The performance issue came up after the update of the SAP GUI.

Best regards

Matthias

Hello Matthias,

I don't see the trace-file, can you do a search in the file for "Aggregated frontend interpretation time", and paste these entries into the reply?

It should read something like

"

<84=Performance: Aggregated frontend interpretation time :          2745

ms

<84=Performance: Aggregated server response time         :          5835

ms (for 12 roundtrips)

<84=Performance:                                         :

~~~~~~~~~~~~~~~~

<84=Performance: Complete request answer time            :          8580

ms (from first frontend request to last R/3 answer)"

Regards,

Jude

Hallo Matthias,
I see your trace-file now.

The results show:

<258=Performance                       : Aggregated frontend interpretation time :           609 ms

<258=Performance                       : Aggregated server response time         :         12406 ms (for 5 roundtrips)

<258=Performance                       :                                         : ~~~~~~~~~~~~~~~~

<258=Performance                       : Complete request answer time            :         13015 ms (from 345752875 ms to 345765890 ms)

<258=Performance                       : ----------------------------------------------------------

So I can see that the SAPgui here is not the issue. The data spends 609 ms at the gui side,but 12406 ms at the server-side.

This is not something the gui can influence,but the application needs to take a look.

Some notes you might find helpful.

HI Jude,

again thanks a lot for your time.

The performance issue occurred only after installing the new SAP GUI version. With Version 4.30 there was no performance issue. That's why I have doubts that it is only a problem with the server.

After entering a value on the screen the ALV is updated in no time, but the HTML takes so long.

Ok, I will tell the customer that they should have a look on the server side.

I really appreciate your efforts!

Best regards

Matthias

No trouble Matthias, the performance trace is always a good starting point.

Kind Regards,
