Would you settle for a CRAY Y-MP8/864?

Same setup, using the UNICOS "scc" compiler with -h inline,aggress,align:

MACHINE                    FULL DES               DES WITHOUT IP and IP-1
=========================================================================
CRAY Y-MP8/864              49,100 bytes/sec       84,300 bytes/sec

Raw data (output of /bin/time) when encrypting 1,000,000 bytes

                               FULL DES           DES WITHOUT IP & IP-1
