Poul-Henning Kamp authoredRetune SHA2 code for improved performance on CPUs with more ILP and a preference for memory load instructions over large code footprints with embedded immediate variables. On amd64 CPUs from 2007-2008 there is not a significant change, but amd64 CPUs from 2009-2010 get roughly 10% more throughput with this code; amd64 CPUs from 2011-2012 get roughly 15% more throughput; and AMD64 CPUs from 2013-2015 get 20-25% more throughput. The Raspberry Pi 2 increases its throughput by 6-8%. Sponsored by: Tarsnap Backup Inc.
