[mapserver-users] Speed of PostGIS vs Shapefiles in MapServer 5.4

[ritesh ambastha]

Hey, 

The game is all about how you utilizes the best available practices. No
doubt that shapefile usage helps you to render/tile maps at a rapid pace.
But, on the other hand, indexing helps a ton on postgis. My recommendation
is to set up pgpool on few servers and then try to render/tile the maps. It
will be much much faster and convenient than using shapefiles.
