Hi,
This shapefile from the Inspire dataportal
https://geospatial.jrc.ec.europa.eu/geoserver/wad/ows?service=WFS&version=1.0.0&request=GetFeature&typeName=wad%3Alpd_int2&outputFormat=SHAPE-ZIP
contains 226 (multi)polygons, one of them with 516716 ring. It seems that
ogr2ogr can't explode the geometries in a reasonable time. Spatialite-gui did
the job in 2 min 30 sec with
select elementarygeometries('lpd_int2','GEOMETRY','exploded','id_1','id_2');
Perhaps GDAL could be improved as well.
