You might want to make sure DMA is enabled for your hard disk and
particularly your cdrom. The following article describes this among other

I must admit I've never achieved as good speeds ripping as I've heard about
in windows. 1.5 is very poor though. I get at least 2.5x on relatively
old hardware. There's definitely no scratches on the cd, right?
cdparanoia is very good at avoiding skips by reading and re-reading the cd
where necessary but naturally this slows things down a lot.

Something must be wrong here. I get about to 1.2-1.5x (depending on system
load) on a P2 266MHz using LAME to encode mp3. That's using the --r3mix
variable bitrate options which are frequently more cpu intensive than
straight 128kbps. Granted I've heard ogg encoding is not as optimized yet
as mp3 -- it being a newer technology -- but it can't be that much
different. What encoder are you using?
1. What's the load on your PC while encoding? ('uptime' will tell you)
2. What's the load on your PC while not encoding?
3. have a look at 'top' and see how much cpu grip & lame/oggenc are using
