I also recommend enabling rtree spatial indexing if you plan to use shapefile
maps and do a bunch of zooming and panning operations --- this option,
while still marked "experimental" is very stable and can speed up map redraws
when using shapefiles that cover much more area than you intend to view at any
given time. rtree builds a spatial index that makes choosing what parts of
the shapefile to display much faster, but its benefits only show up if you're
doing lots of map redraws while zoomed in to a small area.
How does rtree indexing affect redrawing of weather alerts? Weather
alert redrawing is one of the major drags on my machine. I've been
using rtree indexing for a very long time now, but I've never seen a
difference, as far as weather alerts go.
