Performance regression of GDALWarp due to PROJ>6

[vincentsarago]

Expected behavior and actual behavior.

👋 Dear GDAL contributors and community. First feel free to close this if you feel this isn't the place to report/discuss this. I'll happily move this to the mailing list or maybe to the PROJ project 🤷‍♂️ .

First reported in rasterio/rasterio#2121 and linked to #1662 . Basically we are experiencing a huge performance downgrade when using GDAL>=3 with PROJ >6. We understand the changes needed for PROJ >6 and are really happy to have more precise coordinate transform 😄 . I think the main performance issue with Gdal Warp or warpedVRT is that it doesn't cache the coordinate transformation. I'm not sure such a thing is possible 🤷‍♂️ but looking at the log it seems that GDAL is calculating the same pipeline multiple times. I'm not even sure why it does it multiple time...

Use Case
I'm mostly using GDAL for project involving Dynamic Tiling from COG (non aligned with Grid) and thus we are looking for high (or relatively) performance for small parallel warping tasks that may or may not involve data caching.

Steps to reproduce the problem.

GDAL 3.2 PROJ 7.1 (centos)

Thanks for your time and feedback 🙏

[jratike80]

It seems that you have noticed that GDAL project prefers to discuss on the mailing list but you still decided to try to discuss in the bug tracker. But the GDAL community is really there, not here.

Can you find anything usable from other Proj 6 migrations, for example https://mapserver.gis.umn.edu/id/development/rfc/ms-rfc-126.html
and
http://rgdal.r-forge.r-project.org/articles/PROJ6_GDAL3.html?

[vincentsarago]

Hi @jratike80 as mentioned in the issue template, we can still use this place to propose feature or report bug! To me this issue feels like a real issue (coordinates transformation pipeline being recalculated over and over... if I'm right 🤷‍♂️).

I'll have a look at your links 🙏. Feel free to closes if you do feel that this is not the the right place to discuss ☝️

[sgillies]

Let's keep this open but also ask on gdal-dev too. I think there are enough PROJ developers there to help.

[jratike80]

Have you already tried to use the pipeline instead of -t_srs?

+proj=pipeline +step +inv +proj=utm +zone=15 +ellps=GRS80 +step +proj=webmerc +lat_0=0 +lon_0=0 +x_0=0 +y_0=0 +ellps=WGS84
