+# SHA256 performance improvement over compiler generated code varies
+# from 40% for Sun C [32-bit build] to 70% for gcc [3.3, 64-bit
+# build]. Just like in SHA1 module I aim to ensure scalability on
+# UltraSPARC T1 by packing X[16] to 8 64-bit registers.
+
+# SHA512 on pre-T1 UltraSPARC.
+#
+# Performance is >75% better than 64-bit code generated by Sun C and
+# over 2x than 32-bit code. X[16] resides on stack, but access to it
+# is scheduled for L2 latency and staged through 32 least significant
+# bits of %l0-%l7. The latter is done to achieve 32-/64-bit ABI
+# duality. Nevetheless it's ~40% faster than SHA256, which is pretty
+# good [optimal coefficient is 50%].
+#
+# SHA512 on UltraSPARC T1.
+#
+# It's not any faster than 64-bit code generated by Sun C 5.8. This is
+# because 64-bit code generator has the advantage of using 64-bit
+# loads(*) to access X[16], which I consciously traded for 32-/64-bit
+# ABI duality [as per above]. But it surpasses 32-bit Sun C generated
+# code by 60%, not to mention that it doesn't suffer from severe decay
+# when running 4 times physical cores threads and that it leaves gcc
+# [3.4] behind by over 4x factor! If compared to SHA256, single thread
+# performance is only 10% better, but overall throughput for maximum
+# amount of threads for given CPU exceeds corresponding one of SHA256
+# by 30% [again, optimal coefficient is 50%].
+#
+# (*) Unlike pre-T1 UltraSPARC loads on T1 are executed strictly
+# in-order, i.e. load instruction has to complete prior next
+# instruction in given thread is executed, even if the latter is
+# not dependent on load result! This means that on T1 two 32-bit
+# loads are always slower than one 64-bit load. Once again this
+# is unlike pre-T1 UltraSPARC, where, if scheduled appropriately,
+# 2x32-bit loads can be as fast as 1x64-bit ones.
+#
+# SPARC T4 SHA256/512 hardware achieves 3.17/2.01 cycles per byte,
+# which is 9.3x/11.1x faster than software. Multi-process benchmark
+# saturates at 11.5x single-process result on 8-core processor, or
+# ~11/16GBps per 2.85GHz socket.
