Subject: slow CD ripping from moving from 2.4.4 to 2.4.17
Date: Mon, 31 Dec 2001 13:42:22 -0500 [thread overview]
Message-ID: <3C306B3E.24055.F50EE@localhost> (raw)
Hello.
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).

I am using a Pentium I 233 with 32MB of RAM. I have an Advansys

Anyone have any ideas? Anything I can do?
Thank you ahead of time to anyone willing to help.
