How fast does your iTunes encode...?

Depends how many other processes/apps are running and how fast the CD is (some are limited to lower speeds). I can usually peek at 15x (mainly around 14.2x - 14.8x) with only iTunes and the Finder open. That's on an 867MHz G4 tower w/ a Combo drive and 640MB RAM.

I have an 800 DP, 600MB RAM and get 13/14 ish. I guess That means it's not DP enabled. Strange - I'd have thought Apple would have DP'd it seeing as they're making such a thing of both the software that comes with OSX and Dual Processing being the way forward.

Actually, it is DPed. It takes itself one full processor! That's the difference between your and mine setup! If I only run iTunes, I get around 13x, if I run the usual load of Apps, I have around 10x. You could run more apps at once and have less impact on iTunes since it has nearly a whole CPU just for itself, while mine will have to share the CPU with more apps.
DP-ready apps does not automatically mean that they use both processors. Most do, but especially encoders often just take one CPU only for themselves while the OS and other apps are mainly running on the second CPU. A great thing if you do lots of encoding and have to work while you are doing it!

We have the same Mac yet I have 1.5GB RAM and mine is slower. Oh dear. I think my Mac deserves a Low Level Format anyway. There's far too much crap on my HD that's unnecessary.
Thanks for the feedback though. That's exactly why I started this thread.

I noticed, like others, that on single CPU machines, it greatly depends on how many other programs are running while you encode. If you have enough deamons running, like, f.e., Spy, NetMonitor (no deamon but kinda) and stuff like that, it might also draw from the speed. You could increase the thread priority of iTunes, but I wouldn't recommend that...
DP G4 1 gig easily plows thru at over 20x. It typically starts at around 12-15 and then very quickly picks up pace in its indicated speed up to around 22, sometimes as high as 25/26. I could not believe it when I saw how fast it was moving. I could barely put the CDs in fast enough after being used to taking coffee breaks for the iMac. I did not do a bunch of tests, but working in the background and turning on the visualization did not seem to slow it down much if at all. ALso, different encoding qualities didn't slow it down either, unlike the iMac. Finally, proof that Altivec is good for something (hint: Altivec in Photoshop is a lot of hype, I've tested it to death).
My iMac only got around 2-3x and my G4 450 around 4-5x.

Actually, iDVD is probably more of proof to AltiVec. As Apple itself said when they first released it at MWSF '01, most encoders encoded at 25x (not the traditional meaning -- 25x means it takes 25 hours to encode one hour of DVD video), but Apple managed, through software (hint: AltiVec enabled) to take that down to 2x. With iDVD 2.0, they brought it down to 1x.
iDVD is much more amazing, if you ask me.

I'm on the verge of burning my first DVD. Seeing as iDVD 2.0.5 pre-encodes the mpeg2 files in the background, the burning process now only takes the time to burn 4.2 GB of data onto a DVD-R. But I'll be timing it to seehow long it takes.
I might start a new thread actually
Not a bad idea that, nice one son.
