Maybe some optimizations are possible now but I wouldn’t expect any spectacular results - but if you posted specific ImageMagick commands you are running maybe we would be able to help optimize them
=> We are using phpThumb for image operations which internally uses imageMagick.
We are listing following two phpThumb image operations,
fltr[]=crop| l | r | t | b
fltr[]=size| x | y | s
While these operations are executing, we are getting following imageMagick command running in background,
~/imagemagick-talos-6.9.1/bin/convert -density 150 -background #FFFFFF -quality 95 -interlace line ~/<IMAGE_PATH>/e8879e80-2921-478f-b705-a980db6699af.jpg[0] jpeg:/tmp/pThumbbFblWR
Please let us know if you need any other details…
