The Xing encoder is not a reference in term of quality. It's right that it's
fast, but now the new FhG engine is as fast as xing, but with a better
quality.
Yes, Xing cuts corners. An example is that it only uses long blocks, and
thus doesn't compute short ones.
Yes, it contains a lot of assembler and mmx code.
And yes, there is a chance to get similar speed but with a lot higher
quality with lame, one day. The priority with Lame is quality, so quality
improvments are made first. Before optimizing to mmx a function, we must be
sure that this function won't be upgraded soon, this is why there is only a
few mmx on Lame.
