It contains numerous performance related enhancements and is at least twice faster in JPEG compression/decompression than original libjpeg on platforms with MMX/SSE instruction set. It has same API/ABI like original libjpeg and also runs on non-SSE platforms where is around 25% faster. http://sourceforge.net/projects/libjpeg-turbo ==== We should evaluate this library and see if we can replace libjpeg with it for improved performance.

If somebody would make a format with JPEG style encoding and compression I would agree with you. But as far as I can tell it does not exist, all other mainstream formats make use of only zlib compression. And JPEG is unfortunately the best format for images with large amounts of color. I would be happy if you could prove me wrong though. + #4: P Linnell (mrdocs) (2010-09-18 22:53:21) + packaged in : https://build.opensuse.org/package/show?package=libjpeg-turbo&project=home% + 3ALazy_Kent -- openSUSE Feature: https://features.opensuse.org/310410
