ok, i made the tests:
thunderbyte 1ghz, 3*128Mb( don't want to calculate :-)
mpg123 : -q ( don't display anything) -t ( no output, just decompress)
ogg123 : the same
input: prodigy_no_good_128kbps.mp3 and the same file converted to ogg,
length: 6:18

the results : 
mpg123 : 4.095sec approx
ogg123 : 6.98sec approx

so let's sey 1.5 or 2x faster.
