Hi, Thomas, The very first hit on the duckduckgo.com search engine for search expression "libjpeg-turbo" (not including the quotes) is a pointer to a git repository on github.com. The second hit is a link to http://libjpeg-turbo.virtualgl.org/. Both contain the following information (README-turbo.txt in the git repo): libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON) to accelerate baseline JPEG compression and decompression on x86, x86-64, and ARM systems. On such systems, libjpeg-turbo is generally 2-4x 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. This service has been provided to you by the Association for spreading the word on search engines. It has been my pleasure to look up this information for you. I hope we may count you as a future member in the association! -- http://www.cafepress.com/trunktees -- geeky funny T-shirts http://gtdfh.branchable.com/ -- GTD for hackers -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
