+Starting with version 1.1 released in June 2011, default builds of
+crypt_blowfish invoke a quick self-test on every hash computation.
+This has roughly a 4.8% performance impact at "$2a$05", but only a 0.6%
+impact at a more typical setting of "$2a$08".
+
+The large speedup for the original Pentium is due to the assembly
+code and the weird optimizations this processor requires.
+
+The numbers for password cracking are 2 to 10% higher than those for
+crypt_blowfish as certain things may be done out of the loop and the
+code doesn't need to be reentrant.
+
+Recent versions of John the Ripper (1.6.25-dev and newer) achieve an
+additional 15% speedup on the Pentium Pro family of processors (which
+includes Pentium III) with a separate version of the assembly code and
+run-time CPU detection.
