Because binary for multithread operation from profile edition usually modification (the profile optimization effect at the time of MT is low in edition,)
Correcting the description mistake of the cord/code for MT of mapping0_forward
Executing loop unrolling with mdct_forward, mdct_backward and mdct_butterfly_generic under multithread operation environment

You ain't kiddin'!

Lancer 2006 09-15 is out.
  uhhh ...

I haven't even yet unzipped the previous version... and now a new build...

Not that I despise BlackSword and his (her?) attempts... domo arigato gozaimasu !

2006/10/05 Lancer 20061005:
- Updated ICL to 9.1.030
- Improved MT optimization code for mapping0_forward
- Tweaked compile options
- Suppress some compiling warnings
- Discontinue GCC support

This release is memorial to me as this binary (with -q4) runs faster than 100x on my new machine.

Many thanks to 637 (Blacksword) for the brilliant achievement!

This is really impressive. I remember the old time (pre-RC3 encoder) when Vorbis was painfully slow: x1,5 max on my Duron 800 - up to 3...4 time slower than musepack (not present in this big benchmark), and same speed than LAME --alt-preset extreme.

Sadly to read but it's more truely as a number of previous versions not worked after GCC correctly.
But under wine oggenc2.exe will work anyway.

Man, that truly sucks. This should be written with GCC intrinsics, not ICC. Anyone tried building it with the linux version of ICC?

Hmm. On my AMD 2400 it is slower (1x-2x) than ver 2005 11 21
Is it ok?

I've made a little comparison between standard

Anyone knows where to get one of these optimized vorbis builds for Linux?. Can this patch be applied to vorbis' source code and then be built? Using which compiler?

Thanks in advance!

Yeah, I wanted to modify the title of this thread but couldn't.

Intel C/C++ compiler. I'm not sure whether if it can be compiled with the linux version of the compiler.

He dropped GCC support a while back, didn't he? Or was it just code that's untested on gcc?

Current Lame versions (3.98) can be compiled in 64bits mode, that is how I am using it most of the time.
Using VC8 as a compiler, it increases encoding speed by about 20% compared to 32bits mode.

While trying to sound as un-redundant as possible, I observed speeds as high as 24.2x (primarily in the range of 16-20x), compared to only 10.0'ish from what I remember last... and while I didn't run actual comparisons of the files using any kind of sophisticated process, I did ABX and compare bitrates/qualities of files using both aotuv-b5 and the latest lancer build and was unable to distinguish between the two.  Beautiful  ... thanks guys!
