Evaluate switching to libjpeg-turbo

Feature state

openSUSE-11.4
Done

Description

Quoting http://fedoraproject.org/wiki/Features/libjpeg-turbo:
====
libjpeg-turbo is fork of the original libjpeg project. 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.

====
We should evaluate this library and see if we can replace libjpeg with it for improved performance.

no the continude use of jpg format only continues the use of a file format that should have died out a few years back

Can you present a good alternative to JPEG? 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.

We have libjpeg-turbo as default for some time already.
