Javier,
for gdal_translate to COG, both should be equivalent.
for gdalwarp, -wo NUM_THREADS=ALL_CPUS -co NUM_THREADS=ALL_CPUS (ie
enabling multithreading for warping and GeoTIFF output) will be
equivalent to --config GDAL_NUM_THREADS=ALL_CPUS
Note that you can also do gdalwarp directly to COG. This should do the
right things

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.
