[PATCH] Fix 'Writing huge polygon can be very time consuming'
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?
default → OGR_SF
shape writing added
