I've tried Imagemagick to generate web-thumbnails from big pictures (>5M😎, and it takes too much time to produce a thumbnail for the browser. I noticed that it's the reading that takes the time.
Is there any way I can make it faster?
My server has 1.4GHz cpu, 0.5GB RAM, and RH 7.0, so I guess it's not the hw that makes it slow.
