Hi SAP Colleagues
I am trying to improve performance on our ECC / Portals system for remote users and when tracing on the backend ECC6 systems, I can see a lot of lost time around the activity RFC/coms activity. Specifically, I can see that around 3.5 minutes was 'lost' between the following components. I am trying to find a technical explanation so that I may address any specific area which could help me diagnose. For example, does (or indeed could) this point to a problem with RFCs or with the network? If that is the case, does anyone have a useful nect step (e.g. delete old RFCs)...
Any assistance would be gratefully received.
Regards
Des

THere is a known issue with OLE_FLUSH_CALL performance in SAPGUI 720.
This has been solved with 730 SP01.
Could you try to adress your performance issues <by upgrading the SAPGUI to latest avail ?

Hi Des,
We have similar problem in our setup, ABAP trace shows lots of time spent on Client OLE_FLUSH_CALL. Did managed to resolve this issue in your system.
It would be gr8 if you can share your thoughts.

Hi ,
We have a similar issue when accessing Interactive forms from the portal through an ABAP webdynpro. The trace that was run identified OLE_FLUSH_CALL and SESSION_MANAGER as taking the maximum amount of time when trying to display any data from the webdypro in portal.
When trying to Debug this, I did not find that the webdynpro was directly calling OLE_FLUSH_CALL. However OLE_FLUSH_CALL was in fact called from a standard program RSTPDAMAIN.
Could anyone shed some light on how we can check where OLE_FLUSH_CALL is actually getting called from as the call stack does not actually lead back to the webdynpro at all.
Hi There,
You can give a go with following options:
1. Select low speed connection option in SAP gui while login to SAP system.
2. Make use of appropriate application server.
Hope this helps.
