Try setting GDAL_CACHEMAX to 150 (6048 * 4032 * 3 = 73 MB. and a x 2
security margin)
This reduces the time into 4 s.
Quite a bit reduction from several hours.
Maybe the default is too low? 150 MB does not seem much.

I warped an image for which I estimated a geotransform. I'm wondering
why it took so long (hours).
My source image is a jpeg, lets call it src.jpg. I add the geotransform
as a jpgw-file.
This goes fast:
gdal_translate -of JPEG src.jpg test.jpg
Input file size is 6048, 4032
