Hm. I can't get better than 1.4x rip speed out of it with a stock SuSE
10.1 kernel (2.6.16). It's also using truckloads of cpu, whereas the CD
rippers that came with this distro use a percent or two.

What command did you use to rip?

Jan Engelhardt
The ripper he's using is ripoff I assume (source code here: extraction functionality contained in src/RipOffExtractor.c) . It uses libparanoia to do its job, like the cdparanoia command. On my system, ripoff has high CPU usage with a 2.6.16 kernel as well, but it reports a 9.0x rate on average.
Could the fact that it has such high CPU usage be a possible reason I am experiencing a slower ripping speed (1.2x) when the patch that was git bisected is applied?
