When I read this on my machine it reads the image in 1 second and takes 22 seconds to write the image. The reason the png writer is taking so long is probably due to the fact that is is compressing the image. This is still nowhere near your duration. Are you doing the conversion on a really old machine? It is also possible that Magick.NET cannot allocate enough memory and uses the disk. What is the amount of memory in your machine? I ran my tests on a machine that has an Intel Core I3-2120 and 8GB of ram.
