Can Web-Dynpro ABAP handle deep structures in a good performance ?

I have defined a deep structure in the data dictionary with a table in

it. I want to send this to the frontend, which is called by RFCs and is

written in JAVA or ABAP Web-dynpro. Now the question comes up, whether

the deep structure can be interpreted by the frontend or not and is it

a problem of performance to send sutch a structure.
