  * status:  new => needs_review


Comment:

 See branch "benchmark" in my public repository.

 Preliminary results for me on openssl 1.0.0e as patched by Fedora 15,
 running on a Core2 Quad Q8200 suggest:

  * Running openssl 1.0.0's AES_ operations manually seems to be about 5%
 faster than running them via EVP_. Oops!
  * For the kind of cell crypto we seem to do, Openssl 1.0.0's AES_ctr128
 implementation seems about 5% better than the counter implementation we've
 got now.  Oops!

 Sidenotes:
  * It sure might have been a good to use the 'recognized' field to avoid
 doing SHA1; it makes our middleman cell crypto performance about as fast
 as our AES performance.
