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.

[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).
