  Adjust performance claims
  
  Document the latest benchmarks on the Nexus 5X and change the "2-4x"
  overall claim to "2-6x".  The peak performance on x86 platforms was
  already closer to 5x, and the addition of SIMD-accelerated Huffman
  encoding gave it that extra push over the cliff.

  %description
  libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2,
  NEON, AltiVec) to accelerate baseline JPEG compression and decompression on
  x86, x86-64, ARM, and PowerPC systems.  On such systems, libjpeg-turbo is
  generally 2-6x as fast as libjpeg, all else being equal.  On other types of
  systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by
  virtue of its highly-optimized Huffman coding routines.  In many cases, the
  performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs.
  
  libjpeg-turbo implements both the traditional libjpeg API as well as the less
  powerful but more straightforward TurboJPEG API.  libjpeg-turbo also features
  colorspace extensions that allow it to compress from/decompress to 32-bit and
  big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java
  interface.
  
  libjpeg-turbo was originally based on libjpeg/SIMD, an MMX-accelerated
  derivative of libjpeg v6b developed by Miyasaka Masaru.  The TigerVNC and
  VirtualGL projects made numerous enhancements to the codec in 2009, and in
  early 2010, libjpeg-turbo spun off into an independent project, with the goal
  of making high-speed JPEG compression/decompression technology available to a
  broader range of users and developers.
