[Qgis-user] shapefile render speed

when you say that one of them is larger. what do you mean. do you mean larger extent, number of features or size of file. 

what i wonder is if it could be that the fast one has less complex features with less vertexes per feature. the size of the actual .shp file can give a hint.

What factors affect the rendering speed of ashapefile?  I ask because I have 2 shapes file with roughly the sameextents and the same number and type (polygon) of features.  I createdspatial indices for both but one of them, actually the slightly largerone, renders much faster?
