I am looking at improving response time for page loads in a browser and
thinking of progressive rendering.

I would like to know the following:
    1. Many browsers support progressive rendering, any idea how exactly it

    2. Currently, I think webkit displays HTML pages in two passes. First in
Low Bandwidth Display where all the java scripts and CSS are skipped and
once all the external JS and CSS are available it does a second pass where
the complete document is rewritten applying all JS and CSS. So, webkit makes
it look progressive by first displaying a page without scripts and CSS which
is fast and then rewriting the complete page once all the resources are
    I would like to know if anything more can be added to this?

Thanks in advance,
