Processing speed of NConvert is much slower than XNConvert
Posted: Mon Dec 08, 2014 10:25 am
Hi,
Actually I am testing NConvert to process a large collection of images.
7 actions are defined: Conbright, Resize, Gaussian Blur, Adjust, Sharpen, Change Color Depth, Crop.
Image is saved as TIFF Revision 6, CCITT G4.
Batch line looks like this: nconvert -conbright 15 -ratio -rtype lanczos -resize 70%% 70% -gauss 5 -brightness 23 -gamma 1.05 -sharpen 96 -binary nodither
Processing time with XNConvert on my Mac takes less than a second per image.
However, when testing the same actions on my server using NConvert (launched from .NET command line), this takes multiple seconds on a fast server.
What am I doing wrong?
Peter
