+# Accurate performance measurements are problematic, because it's
+# always virtualized setup with possibly throttled processor.
+# Relative comparison is therefore more informative. This module is
+# ~60% faster than integer-only sha512-ppc.pl. To anchor to something
+# else, SHA256 is 24% slower than sha1-ppc.pl and 2.5x slower than
+# hardware-assisted aes-128-cbc encrypt. SHA512 is 20% faster than
+# sha1-ppc.pl and 1.6x slower than aes-128-cbc. Another interesting
+# result is degree of computational resources' utilization. POWER8 is
+# "massively multi-threaded chip" and difference between single- and
+# maximum multi-process benchmark results tells that utilization is
+# whooping 94%. For sha512-ppc.pl we get [not unimpressive] 84% and
+# for sha1-ppc.pl - 73%. 100% means that multi-process result equals
+# to single-process one, given that all threads end up on the same
