How to speed up space partitioning in postgis? hello, here is the result : "POSTGIS="1.5.3" GEOS="3.3.2-CAPI-1.7.2" PROJ="Rel. 4.8.0, 6 March 2012" LIBXML="2.7.3" USE_STATS". I could not find any relevant addition to union in GEOS recently. I found one speedup in polygon unions, but I'm not merging polygons, and this speedup seems controversial. I absolutely don't want do union my polygons as I have to add values for overlapping polygons. |

How to speed up space partitioning in postgis? by collecting the linework and doing an union with an empty geometry, I can do it in 800s : st_union(st_collect(geom), st_setsrid(geomfromtext('POINT EMPTY'), 900913)) that's almost 20 times slower than the ESRI stuff. |

How to speed up space partitioning in postgis? I'm not really fan of mailing lists, moreover, it might also be an GEOS problem, who might complain about JTS, well, I prefer keeping the problem open. |
