-- only information that is shown slows down the display. So duplicating 
without style-file will slow down the display speed.
However the default style is anyhow really overloaded. The first thing 
to do is to put highway exits up to 18 or 19. Then I would look to 
increase some other road types by 1-3.

Such thinkgs have nothing to do in default style IMHO as they are 
useless for non car users. Especially once widespread mapped resolution 
21 is too early. Not before 24 I would put things like traffic_lights 
and their like. However all of this only really works well with typfiles.

You should tryout the default style drawing speed in Germany or the 
Netherlands - other places detail level will sometimes catch up, and so 
to say - less is more. I a country is 100% street and waymapped, then 
the current style is far too overloaded in low resolutions.
