[PATCH] Fix 'Writing huge polygon can be very time consuming'
|Reported by:||richengel||Owned by:||warmerdam|
I tested a version of ogr2ogr which had elapsed time timers at key points in the code. I tested converting the nos80k shapefile (see issue #2428 - multipolygon with 43K parts and 2.5M point). I used the organizePolygons from r14734 with OGR_ORGANIZE_POLYGONS set to ONLY_CCW & get: Overall time: 1376.6 s Read time : 5.0 s (organizePolygons : 1.0 s) coordinate transform time : 1.7 s Write time : 1369.6 s - SHPRewindObject : 1368.5 s If one can assert that the geometry is correct is it necessary to perform SHPRewindObject?
