I have a general question regarding performance in web dynpro java applications. We have an application that reads data from a file on the presentation server, parses it, does some heavy calculation of the data, then spits it back out to another file. Currently the calculations of the data are implemented in the Component Controller of the web dynpro application. We are starting to see some performance degradataion as larger files are being processed. Is there a performance impact of doing these calculations in the Component Controller vs creating a bean model? Would doing these calculations in the bean make things slower/faster/no visible difference?
Any thoughts would be appreciated.
