+# It was noted that Intel IA-32 C compiler generates code which
+# performs ~30% *faster* on P4 CPU than original *hand-coded*
+# SHA1 assembler implementation. To address this problem (and
+# prove that humans are still better than machines:-), the
+# original code was overhauled, which resulted in following
+# performance changes:
+#
+# compared with original compared with Intel cc
+# assembler impl. generated code
+# Pentium -16% +48%
+# PIII/AMD +8% +16%
+# P4 +85%(!) +45%
+#
+# As you can see Pentium came out as looser:-( Yet I reckoned that
+# improvement on P4 outweights the loss and incorporate this
+# re-tuned code to 0.9.7 and later.
+# ----------------------------------------------------------------
+# Those who for any particular reason absolutely must score on
+# Pentium can replace this module with one from 0.9.6 distribution.
+# This "offer" shall be revoked the moment programming interface to
+# this module is changed, in which case this paragraph should be
+# removed.
