![]() The speed was nearly 0.7 iterations per second ( 0.689ips).It reports that it ran 10 iterations ( 10i).Since I don't have OpenMP enabled, I had only 1 thread ( Performance:).The -bench 10 part tells it to run that same command 10 times in a loop and then print the performance results: This command with -resize 500% tells ImageMagick to run the convert command to scale the built-in IM logo: image by 500% in each direction. For example: convert logo: -resize 500% -bench 10 logo.png You can now also use the builtin -bench option to make ImageMagick run a benchmark for your command. So if you have a quad-core system, and resize an image, the resizing happens on 4 cores (or even 8 if you have hyperthreading). When OpenMP is enabled, ImageMagick commands can execute in parallel on all the cores of your system. There's another feature that could help you, called OpenMP (for multi-processing). ![]() Or if you build the package yourself from the sources, make sure OpenCL is used. If it doesn't you should look after getting the most recent version of ImageMagick that has OpenCL support compiled in. Should also give info about supported features. If it does (like mine), you should see something like this: FEATURES HDRI OpenCL You should check if your ImageMagick installation comes with OpenCL support: convert -list configure | grep FEATURES ![]()
