Hi Meera,
Performance issues with WebDynpro ABAP can have several root causes:
* high frontend time (slow browser rendering)
* high network time (too many roundtrips, small bandwidth)
* high backend time (slow ABAP application, inefficient database accesses)
There are several tools:
* in the WebDynpro window, click Ctrl+Alt+Shift+h to get a help on available tools. Ctrl+Alt+Shift+p is for performance, f.e. with frontend time. Others give information on complexity of DOM
* Task Manager on your frontend PC to get impression on frontend CPU time
* HTTPWatch to monitor HTTP-traffic to and from frontend
* STAD on the ABAP backend to get statisitcal information on user interaction step
* ST05 and SAT on ABAP backend for database and ABAP
What can be done:
* Often the displayed screen is complex. Reduce number of columns in lists, input fields, number of displayed lines, number of screen elements. Load any screen information (tabs, table data) only on demand, that is when the user wants to see it.
* Reduce number of roundtrips between application server and frontend to 1 or 2 per UI-step
* Do the usual performance optimization for the backend application
Best Regards,
Randolf
