This reduces performance of iterative modes dramatically. I'm not sure what the right approach for dealing with this is.

However for this to be a full defense it would be necessary to ensure the tables were entirely loaded into cache, which is not guaranteed by the normal SSE prefetch instructions. (Or prefetch instructions for other CPUs, AFAIK). Much more importantly, it provides a 10% speedup.

Sadly, this also confirms that OpenSSL's AES is much faster than Botan's: AES-128: 115.032 [core] 152.994 [openssl] AES-192: 98.6724 [core] 130.087 [openssl] AES-256: 86.6348 [core] 113.608 [openssl] Definitely some improvement can be made there! :(
