Ticket #56 (closed enhancement: invalid)
ST_Buffer slow for large buffers, can be made faster
|Reported by:||pramsey||Owned by:||pramsey|
Description (last modified by pramsey) (diff)
What steps will reproduce the problem? 1. take a smallish geometry with somewhat dense vertices 2. buffer by a distance many times larger than the average inter-vertex distance 3. wait
A process that repeatedly buffers outwards, simplifying the output at each step, will return much faster than a one-step process. if your buffer distance is 1000 times your intervertex distance, try doing buffer(1), simplify(1), buffer(10), simplify(10), buffer(100), simplify(100), etc.
