The unmodified OpenSSL (used in e.g. libdes) gets about 500kbps for 3DES
encryption on my PPro 233 - if you enable the asm optimizations per my
patch sent to -current a few weeks back, it brings it up to about
1900kbps. Blowfish is much faster that this for the same key strength,
although I don't have exact numbers to hand.
