Bruce,

On your web site you claim 17.8 cycles/byte on a pentium pro.
I'm not sure what this means since these processors do
instruction caching/pipelining and data caching. If
I were to use a 200 MHz PPro then this apparently translates
to about 11 MBytes/sec. This seems slower than RC5 which
does about 15 MBytes/sec according to a prior email by
Eric Young. Is this accurate? BTW, does the performance
vary by key size?

- Alex
