I am working on a proof of concept to determine whether using flex to develop portlets is a feasible idea. One immediate roadblock I have noticed is that when I try to load several portlets (HelloWorld-like complexity / about 40KB) in my portal, they all take about 10 seconds to initalize. If it matters, I am using LifeRay. So my questions: Has anyone tried creating and running several flex portlets at once? Is this kind of slow initialization speed expected? Any suggestions on how to speed up initialization?
