(not recommended unless you want your CPU explode):
-r 16 -f -6:-6 -A all -m 7 -w --chroma-qp-offset 2 -p 3 --progress --b-pyramid --me esa -8 --mixed-refs -t 2 --b-rdo --bime
What did I say about "slower is better"? --me esa isn't any better than --me umh, even if you ignore cpu-time entirely.

Except that once you turn off rdo, cavlc isn't any faster to encode than cabac is. So it's trading 10% bitrate for... a little decoding speed? (Which would be a valid reason if it were actually why that option was chosen, but I have to assume that it's not so.)
