[gdal-dev] multithreading

[Javier Jimenez Shaw]

Hi

I am running a gdalwarp from UTM xx to EPSG:3857 and later a gdal_translate
to COG (the input is a normal GeoTIFF). Two steps. All inputs and outputs
are TIFF.

Is there any difference between using the config variable
GDAL_NUM_THREADS=ALL_CPUS
than using the creation option for the TIFFs
NUM_THREADS=ALL_CPUS

What is the fastest combination?

Thanks.
