> It seems Geotools has more problems rendering small features.
To optimize rendering speed when zoomed out you can start to look into
producing cut down datasets and switching between them at different scales. You
can do that with multiple layers (each engaging at a different zoom level), or
look at the "pre-generalized" datastore and it can switch behind the scenes for
you.
A few rendering systems switch to rendering directly from the spatial index
when zoomed out (only works for polygons as I understand it) - as long as the
result gives you less data to traverse it would be faster then considering all
the features in the target area as geotools does currently.
