As a totally unscientific answer to this question, I just threw
together a really quick program that encrypted 100 megabytes of data. Using
the CAST-128 and 3DES implementations from our beta Java toolkit here at
Entrust, it took 47 seconds to encrypt 100M using CAST-128, and 197 seconds
to do so using 3DES. (Note that Java is legendarily slow, especially for
number-crunching.) The CAST implementation isn't stunningly optimized -
speeding it up is on my to-do list before the final release.
It's a noticeable difference.
