Does R have any built in profiling tools? as grass is just a collection of small C programs the normal ones work fine with it: http://grass.osgeo.org/wiki/Bugs#Using_a_profiling_tool or use a profiling tool at the command line while running ogr2ogr with input=grass and output=shapefile? Nikos wrt your 10hr script: v.db.update must open and close the DB for every time you call it. That is very slow and inefficient. Better is to write all SQL update commands to a file (end each line with a ';') then use that file as input to db.execute so it opens the DB, updates all fields, closes DB again in a single step. see the db.execute man page and v.in.garmin script for an example (where it made a huge improvement).
