Bug#664998: Too much CPU used

[Miguel Colon]

>I cannot reproduce that on my personal box. I have a Duron at 800 MHz with debian squeeze on it. Running mpg123 -v needs around 1% of CPU! There must be something else going on. >Also please note that nowadays, the audio output happily gobbles up way more CPU than mpg123 needs. An example is the ALSA library resampling 44100 Hz material to 48000 Hz.
>Can you produce a profile of your CPU-consuming mpg123 (using the perf tool, for example)?
