Hi,

If you are still struggling with the same old problem could you please finally send the gdalinfo reports of your two input files which are this time:
coastal-2020.tif
5_UK_coastal-2020.tif

Aihe: [gdal-dev] gdalwarp running very slow

Greetings,
I am running gdalwarp on a 6GB (output) and 600MB (input) tif image, the AWS Instance has approx 60 VCPU
It has taken over 6 hours so far - still running, is it possible to optimise this and speed it up??

gdalwarp -r near -overwrite coastal-2020.tif   5_UK_coastal-2020.tif -co BIGTIFF=YES -co COMPRESS=LZW -co BLOCKXSIZE=128 -co BLOCKYSIZE=128  -co NUM_THREADS=ALL_CPUS --config CPL_VSIL_USE_TEMP_FILE_FOR_RANDOM_WRITE YES

 Regards,



Clive Swan
