[GRASS-user] Patch raster maps very slow - Is there a way to speed this up?

I have generated DEM tiles (65ish) from LIDAR data in its natural
projection NC state plane feet (the area covered is about 300 squared
miles).  I have reprojected them into UTM 17 nad 83.  These DEMs are
1m resolution.  I am using r.patch and it has been running for three
days now and it is 45% done...  Would it be faster to stop this
process, patch them in there native projection and then reproject them
to UTM?  I am running GRASS 6.5.
kind regards,
