lots of early research and tuning went in to the setting we have now
dating back to
http://weblogs.mozillazine.org/dave/archives/2002_04.htmlits worth looking into this in an age when a lot more people have
higher speed connections and faster pc's but to do this we should also still do a bunch
of testing and evaluation on slow systems and slow networks if we are
going to change the default setting. the best solution might be to
make the setting more dynamic so slower systems and pc's on slow
connections could get the perceptual advantage of incremental painting,
and higher speed networks and systems could just blast out the content....
a dynamic system would be a lot more work.
