Experiences with CD ripping...


Hi there. I've recently started ripping CD's on my computer. Specs are below. However, when I do so, the internet connection stalls entirely. Has anyone had similar problems? I thought originally that it was because my CPU was being overused but everything else still works (albeit slower). I've tried this with two different browsers: Opera and Mozilla-Firebird.

Computer specs:

Celeron 433 (Mendocino)
196 Mb RAM
Internet connection is 56k dial up via an external Rockwell modem.

Usually when a CD burner is running, it runs with a higher priority. In other words it takes more control of the CPU and everything else takes a back sit. Mine does the same with other programs when I burn using K3b. If it doesn't do that you can wind up with a coaster.

You may can change that by changing the nice setting. That's how Linux gives priorities to programs. I do NOT recommend that though for the reason above, coasters that is.

Help any??

CD ripping costs a lot of CPU time.

When your ripper runs, open another console, and type "uptime", or "w". You should see the load averages of the past minutes.

A load of 0.00 means you machine isn't doing anything. If one process wants to use 100% cpu time, your load will become 1.00. A load of 2.0 is slightly unusable. My AMD1800 with 512 MB ram, gets a load of 6.0 when I'm encoding MP3's with lame (ripping with cdparanoia) I'm really curious what your load is.

Unfornatately, a Celeron processor lacks good multimedia performance. The processor is not expensive, because it's made for simple Office work, and other things that don't require multimedia calculations.

I've run cooledit (a popular windows digital audio editor) once at a 1000Mhz pentium4, and a similar system with a 1000Mhz celeron. Deleting a small part from an 80MB MP3 file, took 3 seconds at the Pentium4, and 10 minutes (!) with the Celeron system.

Dalek, I'm not burning CDs I'm ripping them - to the hard drive. I don't even have a burner on this computer.

Yapp, I understand that it's a CPU intensive task but modem control is not. Not to mention I can still do everything else like play music, open/close programs whatever. It runs slower as you would expect but nothing completely stalls except the internet connection.

I got a load of about 2 using uptime. That was without the extra paranoia settings. I still don't understand why the modem stops working. Everything else seems to work fine but slower. I'd understand if the connections slowed but stopped altogether?

I think you modem is a software-based modem, it uses your CPU for the data modulation! These modems are often called "winmodems", because you need Microsoft Windows software to make the modem work (because drivers only exist for this operating system) You're lucky that your model works with Linux.

I've been looking about winmodems at google, and found an interesting link: http://www.56k.com/reports/winmodem.shtml. It also lists your manufactor, so I think this is the answer..

No it's not a winmodem. If it was then I'd need a driver and I've never installed one. I just plugged it in and off I went. Besides I got it from an ISP. By that I mean the ISP used it to receive calls from clients dialling in. They replaced these ones with a single unit that could take something like 100 calls simultaneously so this puppy became obsolete to them. Definetly not a winmodem.

Let me pose the question another way: Do any of you use a modem while ripping/encoding mp3s/oggs? Did you experience any slowdown or stalling? Actually it was oggs that I was encoding I don't know if that's more processor intensive or not. But other stuff still works....
