Processing time using gdk_pixbuf: 431ms
Same method ported to Mono.Simd: 66ms
That means roughly 6.5 times faster !
- The gdk-pixbuf is an unoptimized standard gdk operation (gtk+ 2.18.1), but I don't think a lot of them are optimized either using mmx or SSEx for this platform (x86-64). Feel free to prove me wrong here.
- Times are averaged.
- Loading and saving times aren't taken into account here, but both are using gdk_pixbuf operations.
- The Mono.Simd method acts on vanilla pixbufs, and results are plain old usable pixbufs, not some kind of memory buffer or whatnot.
- The image attached to this post is not the result of the processing.
