[gdal-dev] vrt performance with 1000's of tiles?

[William Kyngesburye]

I thinking of creating a vrt for approx 19000 geotiff DEM tiles (SRTM).  Any comments on the performance or practicality of this?  Is there a difference in performance between Geotiff and GRASS as the tile format?

Mainly it's so I can easily extract regions for projects, so it would be one-shot gdal_translate runs.
