libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors which uses SIMD instructions (MMX, SSE2, etc.) to accelerate baseline JPEG compression and decompression. libjpeg-turbo is generally 2-4x as fast as the unmodified version of libjpeg, all else being equal. libjpeg-turbo was originally based on libjpeg/SIMD by Miyasaka Masaru, but the TigerVNC and VirtualGL projects made numerous enhancements to the codec, including improved support for Mac OS X, 64-bit support, support for 32-bit and big endian pixel formats (RGBA, ABGR, etc.), accelerated Huffman encoding/decoding, and various bug fixes. The goal was to produce a fully open source codec that could replace the partially closed source TurboJPEG/IPP codec used by VirtualGL and TurboVNC. libjpeg-turbo generally achieves 80-120% of the performance of TurboJPEG/IPP. It is faster in some areas but slower in others. Fix: New port: graphics/libjpeg-turbo a version of libjpeg which uses MMX, SSE, and SSE2 SIMD instructions to accelerate baseline JPEG compression/decompression by about 2-4x on x86 and x86-64 platforms. It is based on libjpeg/SIMD but has numerous enhancements Patch attached with submission follows:
