Feature to raster Python very slow in ArcGIS 10

I've got an ArcGIS 9.3 script that is also to be used in ArcGIS 10 (but not exclusively).
Under ArcGIS 9.3, this script runs quite fast (<1min per raster), but in ArcGIS 10, running time is dramatically longer (>10min per raster).
This is, obviously, not acceptable.

The resulting raster has 7349 columns and 6110 rows.

Can anyone tell the reason behind this huge differnce in processing-time (is it because I'm using arcgisscriping instead of arcpy?).

import os, sys, arcgisscripting
gp = arcgisscripting.create(9.3)

inShape = gp.GetParameterAsText(0)
outRas = gp.GetParameterAsText(1)
field = gp.GetParameterAsText(2)
cellSize = gp.GetParameterAsText(3)
snapRaster = gp.getParameter(4)

#Storing old snapping parameter
oldSnap = gp.snapRaster
#Define snap raster 
#define extent
gp.SnapRaster = snapRaster
oldExt = gp.extent
rasDesc = gp.Describe(snapRaster)
newExt = rasDesc.extent
gp.extent = newExt

gp.FeatureToRaster_conversion(inShape, field, outRas, cellSize)
gp.snapRaster = oldSnap
gp.extent = oldExt
del oldSnap, oldExt
