VIA C3 with the xcrypt-* instructions. This is using a new diff
I have written which makes OpenSSL directly use the cpu instructions
if they are available, right in userland, without having to call to
Two things are apparent. First, this CPU feature is really cool.
Second, the OpenSSL glue above crypto operation has pathetically high
