Oh, that's a good point.  I don't know if that means that the crypto  
code won't use 64-bit optimizations though.

The Crypto++ benchmarks posted by its author, Wei Dai, are:

http://cryptopp.com/benchmarks.html

All measurements are CPU cycles per byte hashed.

Intel Core 2 1.83 GHz, 32-bit mode:

SHA-256: 22
Tiger: 8

Pentium 4 (Northwood)

SHA-256: 41
Tiger: 16

Opteron 2.4 GHz:

SHA-256: 21
Tiger: 7

Okay, and I've just run the Crypto++ self-benchmark script on one of  
our servers (deharo2 -- Pentium 4 3.0 GHz):

SHA-256: 45
Tiger: 15

And on my workstation (Athlon64 2.4 GHz):

SHA-256: 22
Tiger: 7
