1.3 GHz Athlon Thunderbird:

Botan mainline:            71.01 Mbytes/sec
Botan w/attached:          103.80 Mbytes/sec
Botan w/OpenSSL:           133.14 Mbytes/sec

2 GHz P4-M:

Botan mainline:                    49.78 Mbytes/sec
Botan w/attached:                  63.98 Mbytes/sec
Botan w/OpenSSL:                   180.77 Mbytes/sec

Obviously this could be scheduled much better for the P4 (and the
Athlon, for that matter), however I don't know much about Netburst
instruction scheduling. Was only testing on the Athlon until the very
end, so it's possible this is a completely wrong approach for P4
performance, dunno.
