Ripping speed
I've noticed I can rip about .90x play speed with --r3mix with lame 3.89 on a TiBook 550. What I don't understand is why my 1 Ghz P3 can encode the exact same wave file at 5.4x play speed. Windows takes 34 secs and the mac takes 3min 50 secs. I would expect my Mac to be close to Windows, but it's much slower.
Ripping speed
Is the Windows machine ripping the file using the same settings as the mac? The r3mix setting in LAME will severely tax your processor as it tries to make a perfect-sounding file as small as absolutely possible. Default settings for iTunes and most Windows players are usually set for lower quality (therefore more speed).

I ripped one track using iTunes to a wav file. I copied this file over to my windows box. I used "lame --r3mix infile outfile" to encode it both on the mac and the pc. The pc did it in 30 secs at 5.x speed. The mac took 3.x min at .9x speed.
Ripping speed
Ok. I ran a test with two tracks this morning. I used ExactAudioCopy on a pc to extract 2 wav files from a CD. I transfered the wav files to my mac and here are the results.

IIRC, the x86 versions of LAME use inline hand-coded assembly |
