Have you read doc/performance.html? It attempts to

The only encryption currently supported is 3DES. It
is usually fast enough. With a user-contributed
[atch (doc/web.html#patch) you can change to AES
which is faster.
The supported hashes are MD5 and SHA-1. I think
the AES patch adds SHA-256, I'm not certain. I
don't know if there are significant speed differences
there. My guess would be it doesn't matter much,
since encryption is the larger overhead.

See doc/interop.html, then search the mailing list
archive for more recent info.
