This command just took 15 minutes to complete. Why? I don't have the speediest of dev servers but 15 minutes seems a little high.

Here's the command

Code: Select all

convert -debug "All" input.jpg -resize 420x420\> output.jpg

Thanks for your attention

Try rebuilding ImageMagick without OpenMP support. There are a few buggy implementations of libgomp that slows down ImageMagick rather than speed it up. We're using ImageMagick 6.5.7-0 and your command completed in 2 seconds.

Could you point me towards a good tutorial about how to rebuild IM?

Also, if I do that, doesn't my package manager lose track of it?

Thanks,
