The info on the website is about an older version of LAME.
lame -h -b320 x.wav x.mp3 will result in ~1.4x often
on my Pentium166 MMX (at 200 MHz)
VBR is 2 to 4 times slower than CBR
-V1 -b128 -mj -q1 ~0.38x
-V1 -b128 -mj -h ~0.46x
-V1 -b128 -mj -f ~0.62x
or with RH_AMP defined and doing some carefully noise shaping
-V1 -mj -q1 -X6 -Y -Z ~0.13x
But these factors are only rough estimations, they vary
a lot on different music pieces.
