JSF ui:fragment rendered performance-Collection of common programming errors

I have a set of jsf components that are statically generated from a set of excel files (they are updated by business people). Each generated file represents a business object that has slightly different data, and all of them belong to a same class.

In order to render this dynamically, the only solution I found was to set up a bunch of ui:fragment and dispatch to the right component at runtime:

But I found out that the perfomance of this is terrible. I tought that JSF would only render a single component, but it seems that it is rendering all of them and “hiding” the others at runtime.

Is there a more efficient way of achieving my goal? I want to render a single component based on runtime information about a business class (much like an if-then-else), but I can only determine what is the component to render at runtime.

Clarification: what happens is that each component referenced by limites:limites* is a huge complex page with lots of other components. At runtime, the parameter named type' will decide what component to render. But my tests show that if I only render one component, but leave the otherui:fragments` (even knowing that they will not be rendered), it will render much slower than if I remove the components.

So if my page is exactly like this:

it will render much (around 10x) faster than the initial version, even though the parameters are the same. I suspect that JSF will create the entire component tree and only at runtime it will decide (depending on the supplied parameter) if it will render each other or not.

Edit

Almost there. I just need to include my composite component dynamically. I tried evaluating an ELExpression but that didn’t work. What I need is a way of accessing the current scope within the component creation, and using that to generate the proper file name:

//obviously, ELExpressions don't work here
Resource resource = application.getResourceHandler().createResource("file-#{varStatus.loop}.xhtml", "components/dynamicfaces");
