Web resource file downloads and performance

Hi, we just did some basic benchmarking and measured roughly about 700k of
CSS and scripts download for a relatively basic page.

Is there a way to control and limit what's being sent as far as scripts and
css somehow? We've tried using the 'webuiJsfx' attribute:

<webuijsf:head webuiJsfx="false" title="...">

Without the 'webuiJsfx' attribute we found:

603kb transfer, ~3.96s over 5 loads with cache turned off.
749kb (688 from cache), ~5.0s over 5 loads with cache turned on.

With the 'webuiJsfx' attribute we found:
565kb transfer. ~4.0s over 5 loads with cache turned off.
710kb (650 from cache). ~5.5s over 5 loads with cache turned off.

This could be a show-stopper for our external applications that need to go
via SSL (i.e. without caching). What can we do to further reduce this
file-size footprint?
