We tried several way to load an already topologically correct shapefile
into postgis topology .

10k lines loaded
_Using totopogeom : 750 sec
_Using addlinestring : 246 sec
_Manually using addnode and st_addedgemodface : 86 sec.

Still very slow  :-/

Considering manually filling table /and/or using GEOS/or using grass loader.
