[postgis-users] raster efficiency

Hi all,

I am loading in a table a somehow large set of DTM:
14 DTM of 6x9km with a 2m pixel.

I found quite to calculate a profile: it takes approx 1-2 secondes to 
calculate a profile of 4-6 points.

Is there any thing that I can do to fasten the process?

What is the best strategy: having more small rasters or a single big one?

Thanks a lot
