slow TiffWriter performance #3480
Comments
@ebremer there have been several public reports about conversion performance. Over the last months, we have started reviewing various bottlenecks in the writing API for some specific scenarios. Ultimately some large API changes will probably be necessary to ensure

with 6.3.0 (I think it's the same with earlier versions), TiffWriter performance is slow. I'm writing individual tiles out, with LZW compression. The amount of data is small, hardly and IO activity. The final file is perhaps 200MB in size but it takes nearly an hour. Now, my computer is fast 8 cores, 3800X 8-cores, 64GB RAM and a Corsair MP600 M.2 disk. I've notice this issue for some time but wanted to ask about it, knowing a little bit more about TIF file structures now, I'm not entirely sure why the tile TiffWriter performance is so slow.
