Remember that you can't compare the speed of RC5 encryptions with DES
encryptions. The two algortihms are very different. RC5 encryptions
are more expensive to perform, computationally, than DES. You won't
be able to get RC5 going as fast as DES, barring someone discovering
some incredible way to implement it. (This seems unlikely.)

This is why it made sense to go after 56-bit DES before 56-bit RC5.
(Besides the fact that DES is a sexier target, given its widespread
use.)\
