Subject: [pdf] Parallelizing MD5 on Intel Architectures
<quote>
In the case of ”John the Ripper” [1] by which our implementation was
inspired, sourcecode is available for review. On the Xeon machine used
(see figure 1) John reaches about 7.3 million MD5 iterations per second
in a single thread, whereas our 64 bit implementation reaches 33.4
million iterations per second. However, there are some differences
which might affect performance, because John the Ripper builds its
passwords by a more complicated grammar using dictionaries.
An earlier unpublished implementation by the authors of this paper
using OpenSSL performed around 0.8 million iterations per second.

Source code is not available, we do not know what Xeon was tested, but
Is there something that we could make use of?
