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.
