| Post subject: | CD ripping speed |
Are there any tweaks that can be done to enhance the CD ripping speed? Having tried it, I found that with default settings (high quality, Ogg vorbis) it takes about 5 mins per track which is almost an hour per CD. My drive is a DVD-RW CD-RW 48x. I only have about 20 megs of free space on / but plenty in /mythtv etc, so I don't know if this can affect the performance in any way.. Thanks. |

How fast is your CPU? This will likely make the biggest difference to this. Encoding (and/or transcoding) is computationally intensive. Of course if you have other stuff going on at the same time (transcoding, comflagging etc)... 20M free in / is not healthy, could fill up anytime and crash the box, I'd check log files etc to see what you can clear out. |

My CPU is a 2.4 GHz P4, and I have 512MB RAM. So it shouldn't be a performance issue unless the near-full / is somehow hindering the performance. But I assume DVD and CD drives should generally work at full speed straight away in KnoppMyth without any additional tweaks etc? |

Audio extraction never, ever, runs at the max rated speed of the drive. I think 8x-16x is the typical max extract speed on CD/CD-R/CD-RW drives. DVD-Rx drives tend to be a level slower (4x-8x) max audio extract speed. Still, you're seeing about 1x extract speed, so there's definitely a problem. Perhaps the parameters passed are telling the drive to work in a very conservative extraction mode. -brendan |
