Hi,

I think theres no easy way to intercept the rendered result of a single 
component (that contains a lot of other components). But you could put this 
component inside some kind of dummy-page, asynchronously call its url from an 
internal caching-service and store the output using simple I/O streams.

But that would only make sense if the rendering itself is the expensive part.
Are you sure that there's no other way of optimizing your code? Rendering a lot 
of data might also take long because you need to make queries against a 
database. Maybe you haven't cached the data itself yet?
You could also think of reducing the amount of items to be displayed on 
pageload. Is the user able to see all the rendered data without scrolling? If 
not, you could easily use a lazy loading component to load more data if it's 
really needed like these:

        http://www.appelsiini.net/projects/lazyload/enabled.html
        
http://www.webresourcesdepot.com/load-content-while-scrolling-with-jquery/

Keep the rendering as light as possible!

Best,
Christian
