can we use webstart instead of web framework like JSF?

we going to do web based medical transcription project.in starting stage we decided to use JSF but right now we re think about it and we planned to use desktop application because of performance.i have to know can we use webstart for some what big design and size application.i have read faq about webstart in which they mentioned some bugs in web start.

please suggest me?

Performance is a highly unusual -not to say strange- differentiator for deciding between a desktop app and a web app. Both types of applications are so different in capabilities, benefits and drawbacks that performance -which can generally be tuned, and, if necessary, enhanced through more/better hardware- shouldn't be the deciding factor.

I can't comment on any putative bugs in Web Start, because I don't know what those are supposed to be. But I'm sure JSF has bugs, too.
