[SLE] [ot] time to create MP3's? Is my system slow?
[off topic, i know] I have a dual pentium system at home, which I assumed would just rip while creating mp3's. However, I have not seen any benchmarks on how long it should take, so I'd appreciate feedback from the list on what their systems do. Mine took a whole CD, using "abcde" as a front-end, CDparanoia and gogo as the back-ends, and encoded 12 tracks (about 45 minutes of listening time) in about 10 minutes. I am going to do more substantial testing tonight, but I cannot help but think that it should go faster than that - perhaps running Xchat at the same time made it slow down a lot? I dunno. Anyway, I appreciate the advice or any possible configuration options I might have missed. I believe I have SMP and Multi-threading turned on in these programs, and I know I have smp compiled into the kernel (and working).

How much RAM do you have in the system? Did you rip the songs from CD then
convert them to mp3s?
If you say took a CD and rip it directly from CD to finish, then that is a
fast machine. Even if you have 8 Pentium 800Mhz and 2 Gigs of RAM with
10,000RPM RAID cage, it will still take awhile if you have a 24X CD-ROM
drive. The processer can only encode as fast as the CD dumps out the data.
What speed is your CD-ROM? Ussually no matter how fast the CD-ROM is, it
can keep up with a decent CPU/RAM configuration.
On a AMD K62-300Mhz W/176MB RAM and 40X SCSI CD-ROM drive it takes about
30-90 minutes to dump/convert an entire music CD from start to finish. If I
"pre-dump" the music CD onto the Hard drive in .wav format it ussually takes
20-45 minutes for all the wav files to be converted over into mp3 in the
highest sound quality (something like 256KBPS/16-bit IIRC).
Also if you convert into a low quality mp3 not only will you save disk
space, but also it should take less time to convert, but the sound quality
won't be as good. What speed are the CPUs in your system? 9 times out of
10 the CD-ROM drive in the system is ussually one of the biggest bottlenecks
in a decent system, and there is no way I know of to "heighten" the
performance of CD-ROM drives, they have to obey the laws of physics just
like the rest of us. CD-ROM drives can only spin the CD-ROM so fast, even
the new CD-ROM drives you see don't have the performance of a /really/ good
hard drive.
I don't know of any Linux programs that will benchmark your CD-ROM drive.

128 mb ram. I ripped the songs from CD to Wav, then it converts them to mp3 - what quality, I have no idae.

128 mb ram.
That is more than enough
I ripped the songs from CD to Wav, then it converts them to mp3 - what quality, I have no idae.
So it takes 10 minutes to go from .wav to .mp3? ; that is good time. If you are getting a full CD from wav to mp3 in 10 minutes with average to great sound quality I would say that is a good thing. I wouldn't worry about it to much. You might want to check to make sure the mp3 converter is using both processers (sorry can't help you here, don't have an SMP machine), other than that it looks good. If you make sure that the mp3 converting software is running on both processers that isn't really much that you could do to increase performance (besides more hardware:) Lowering the sound quality will help it convert it faster, but most people don't like this option (I personally can't tell the differant between 64 and 256 just by listening to it). Another thing I ussually do is rip the cd to wav while I am at the console (so I can manually put in and take out CD from the drive), then at night when I go to bed have a cron or at job start and convert it from wav->mp3 at the middle of the night. As long as it doesn't take over 5 hours, it is fast enough for me, plus there is a nice hot steaming plate of pure mp3 goodness sitting on the computer when I wake up. You might want to try other mp3 converting software, benchmark a couple of them with the same data, same machines, same processes running and see what you come up with. I don't think you will cut your time to 30 seconds, but you might be able to knock a 1-2 off your 10 minutes if you find a "tweaked" out mp3 converter. Jack

hehehe...I do *exactly* the same thing. Or, I did, until I abandoned gogo...

That sounds perfectly reasonable. Two things: How many instances of gogo does abcde start? You should not start more than two (one per CPU). How fast and what type of CD-ROM do you have? Even with my FPU-challenged K6-III, gogo can often outrun my Kenwood 52x ATAPI CD. It should be noted that 6 months ago, the Kenwood 52x ATAPI could outrun the fastest ATAPI and SCSI-II CD-ROMs on the market, so it's not a slouch, either. -- -=|JP|=- Jon Pennington | Atipa Linux Solutions -o) jpennington@atipa.com | Kansas City, MO /\\ 816-241-2641 x107 | http://www.atipa.com _\_V -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/Support/Doku/FAQ/
