When I run ImageMagick to create an animated GIF from a large number of images, it uses resources such that my i7 system becomes unusable. Within seconds of starting, everything freezes and, ultimately, requires a manual reset of the computer (I can't even kill the process in another terminal due to the sluggishess).
How can I prevent ImageMagick from taking up so much of the system resources? I have already tried using
export MAGICK_THREAD_LIMIT=1 before running it.
