Resolution: wontfix
Status: newclosed

The rendering is indeed super slow, but nothing we can do about that fundamentally since the time is spent in poppler itself.

You can speed up things by adding --config GDAL_SWATH_SIZE 1000000000 to the gdal_translate command line so that rendering of bigger chunks of the image is done (in that case the whole image)

You can also lower the resolution with -oo DPI=300 for example.
