If we have a hardware accelerator chip, than we _already_ have improvements 
with even the worst async crypto layer, since software and hardware 
will work in parrallel.

Thats what i am hoping - and theory points to it. Numbers, numbers
please ;->

There's an OpenBSD paper which demonstrates the usefulness of crypto
hardware for reducing cpu contention.  I can't get to their web site now,
but it's there somewhere under a security link.

Asynchronous crypto layer was written under impression of those paper.
OpenBSD layer is very good, but it has some nitpics some of which are really
not good, but I hope all of them are resolved in my driver.

You can find paper for example there: http://www.madchat.org/crypto/ocf.pdf

And a paper I wrote explains how I fixed many of the problems with the 
openbsd code in freebsd.

In the same proceedings you'll also find a horrible paper I wrote about 
some performance tuning I did in my IPsec implementation that uses the 
crypto infrastructure.
