20% is quite a large performance hit, but within the bounds of reason.
Something to keep in mind, however:

The newer Intel processors have some hardware support for AES. As I
should be acquiring one of those in the near future, I intend to
rewrite the AES package to take advantage; of course, preferably by
exploiting existing working code.

I don't believe any software implementation will get within 20% of the
resulting performance. In other words, you will need to do the same.
Though I wouldn't mind if you use mine..
