+solaris 2.5.1 usparc 167mhz?? - SC4.0 cc -fast -Xa -xO5
+
+For the ultra sparc, SunC 4.0 cc -fast -Xa -xO5, running 'des_opts'
+gives a speed of 475,000 des/s while 'speed' gives 417,000 des/s.
+I belive the difference is tied up in optimisation that the compiler
+is able to perform when the code is 'inlined'.  For 'speed', the DES
+routines are being linked from a library.  I'll record the higher
+speed since if performance is everything, you can always inline
+'des_enc.c'.
+
+[ 16-Jan-06 - I've been playing with the
+  '-xtarget=ultra -xarch=v8plus -Xa -xO5 -Xa'
+  and while it makes the des_opts numbers much slower, it makes the
+  actual 'speed' numbers look better which is a realistic version of
+  using the libraries. ]
