I think very few people care about audio encoder speed in the era of fast multicore processors. 
Hi
Currently I'm using...
Quote
$ oggenc -v
OggEnc v2.83 (Lancer [Nov 14 2009](SSE) based on aoTuV b5)

With a single-core machine.
Is there anything faster out there - for LINUX?
Bump
Has this thread died, or is it a very very difficult question?

I think dutch109 answered that question anyway with a link to faster builds for single core machines.

Did you see dutch109's post above? It has a link to newer, more optimized builds than you are running.

I don't see a link to optimized linux builds, it is a thread about patches.

Unfortunately, it only uses the name of the Lancer, but it works much slower than the original Lancer. Quality is almost the same, all Vorbis encoders provide almost the same quality. libvorbis doesn't use patches from the latest aoTuV versions, just because improvements are barely perceptible, if they are perceptible at all. I don't think that authors of the libvorbis would ignore aoTuV patches if improvements were indisputable.

What is the difference in speed between the current and original builds?

They might also ignore AoTuv changes because they disagree with the result it produces, see the changelog from libvorbis 1.3.2:

   first enabled in 1.3.0; there are a few samples where I
   really don't like the effect it causes.

Noticed bit rate bloat too, Like some samples average 200 ~ 385kbps on AoTuv . Yet libvorbis stays within 100 ~ 190kbps with zero effect to sound quality?.
