+# AES for s390x.
+
+# April 2007.
+#
+# Software performance improvement over gcc-generated code is ~70% and
+# in absolute terms is ~73 cycles per byte processed with 128-bit key.
+# You're likely to exclaim "why so slow?" Keep in mind that z-CPUs are
+# *strictly* in-order execution and issued instruction [in this case
+# load value from memory is critical] has to complete before execution
+# flow proceeds. S-boxes are compressed to 2KB.
+#
+# As for hardware acceleration support. It's basically a "teaser," as
+# it can and should be improved in several ways. Most notably support
+# for CBC is not utilized, nor multiple blocks are ever processed.
+# Then software key schedule can be postponed till hardware support
+# detection... Performance improvement over assembler is reportedly
+# ~2.5x, but can reach >15x [naturally on larger chunks] if proper
+# support is implemented.

+# Performance improvement over vanilla C code varies from 85% to 45%
+# depending on key length and benchmark. Unfortunately in this context
+# these are not very impressive results [for code that utilizes "wide"
+# 64x64=128-bit multiplication, which is not commonly available to C
+# programmers], at least hand-coded bn_asm.c replacement is known to
+# provide 30-40% better results for longest keys. Well, on a second
+# thought it's not very surprising, because z-CPUs are single-issue
+# and _strictly_ in-order execution, while bn_mul_mont is more or less
+# dependent on CPU ability to pipe-line instructions and have several
+# of them "in-flight" at the same time. I mean while other methods,
+# for example Karatsuba, aim to minimize amount of multiplications at
+# the cost of other operations increase, bn_mul_mont aim to neatly
+# "overlap" multiplications and the other operations [and on most
+# platforms even minimize the amount of the other operations, in
+# particular references to memory]. But it's possible to improve this
+# module performance by implementing dedicated squaring code-path and
+# possibly by unrolling loops...
