Firstly, as I (and others) have mentioned, OpenAFS doesn't use DES, it uses an encryption algorithm called fcrypt, which is a DES derivative. Secondly, your assumption that weaker encryption algorithms will be faster to compute is sadly false. Typical DES implementations are significantly slower than AES ones, for example - just compare the output from OpenSSL's speed tool.
