[Geoserver-users] WMS performance

We've successfully set up a rather large and complex set of shapefiles
(about 8GB total, some files >1GB not memory mapped) that are served
by Geoserver as a WMS.

However, we are wondering, are shapefiles the most efficient data
source, performance wise? Or should we look into using PostGIS, or
something else?
