+The performance of JPEG resizing is typically 15x-25x faster than ImageMagick and GraphicsMagick, based mainly on the number of CPU cores available.
+
 Under the hood you'll find the blazingly fast [libvips](https://github.com/jcupitt/libvips) image processing library, originally created in 1989 at Birkbeck College and currently maintained by John Cupitt.
 
-Performance is up to 18x faster than ImageMagick and up to 8x faster than GraphicsMagick, based mainly on the number of CPU cores available.
