Using 2.4.4 up to, I believe, 2.4.14, CD ripping was fine. My Plextor 12/10/32S (S for SCSI) ripped audio CDs at around 25X, even sometimes at 30X. While ripping, my hard drive would work continuously, and so would my CDRW drive. Now with 2.4.17, my hard drive can't keep up with my CDRW drive: everything happens in bursts. My CDRW drive starts ripping as fast as possible, but my hard drive doesn't do anything (0-5 seconds). Then, my hard drive decides to start writing, which stops the CD ripping process (5-8 seconds). Now that the hard drive is done, the CDRW drive continues ripping... for 4 seconds and the process continues over and over again. This brings down the ripping speed down to ~18X, a far cry from the 30X achieved with 2.4.4 and very close to the writing speed of my CDRW drive (12X), which is ridiculous. As stated before, ripping is fine in 2.4.4 (which I still keep around because of this problem). What does help in 2.4.17, however, is manually entering running the 'sync' command ever second or so on another console. This makes the ripping process a lot more "continuous," like 2.4.4. I can't burn CDs in 2.4.4, however, because that freezes up my computer, for some reason. That happens a lot less often in 2.4.17 (but that's another matter). I am using SuSE 7.2 Pro with the latest cdda2wav (1.11a12).
