V2 Live Performance Test 3 and 4
I posted earlier, using my PIII 800. Just got a laptop - here are the results:
Make of computer: ProStar
Operating system: XP Pro
CPU Speed: 2.4ghz
ram:512ddr
Soundcard: Internal
Result for test 3: 1%
Result for test 4: 10%
I once get a result of 8% for test 4, but mostly it has been a very steady 10%. I have an EMI 2-6, which I have not tried out yet.

Test with OSX 10.2.4
Make of computer: TiBook Rev B (Giga) 667/512RAM 30gig HD (4200)
Operating system: OSX 10.2.4
CPU Speed: 667
Soundcard: Internal (CoreAudio)
Sample Buffer: *192 samples* (please note!)
Result for test 3: 5%
Result for test 4: 43%
No dropouts with ~5ms latency -- this seems a tad better than 10.2.3? Will test with Motu later.
Also plan to test with Rambunctious RAM disk for holding the samples (need to get that addt'l 512 MB RAM )
-0
*** Update: adding RAM and a RAM disk did exactly what the intelligent person would predict: had *no* affect on CPU usage, but completely removed the stuttering/skipping you get when a new sample that wasn't loaded is going to play. Bottom line, the powerbook is usable with 1GB + set loaded as RAM disk samples, even for large sets. Hopefully Apple will give us the IBM Power5 and better CoreAudio, and Ableton will give us Altivec

ACER Travelmate 800
Make of computer: ACER Travelmate 800
Operating system: WindowsXP Pro
CPU Speed: 1. gHz
Soundcard: Realtek AC97 Audio DX (12 ms latency)
Result for test 3: 1 - 2
Result for test 4: 9 - 22

Make of computer: ACER Travelmate 800
Operating system: WindowsXP Pro
CPU Speed: 1. gHz
Soundcard: RME Hammerfall (1.5 ms latency) - driver 2.4.3.2
Result for test 3: 4
Result for test 4: 11 - 27
Maybe the RME driver needs an update, but I think these figures speak for themselves.

maybe I should explain this a little bit more...
the CPU on my Acer Travelmate 800 seems to change a lot between the lower as well as higher values. Doesn't matter what application or soundcard I use, it goes up and down all the time. But I think the bottom line is the highest value... and that's not a good figure for such a modern machine. I don't know what's causing this, but I suspect it's the Centrino CPU...
WOW ! My mistake!!!! Great and abnormal good performance...
I couldn't really believe the performance was this bad since all kind of tests show that the Centrino is a very great CPU.... here's what I found out... read on...
When you choose the wrong power scheme under WindowsXP the Acer/Centrino won't perform great. I changed the power option from 'Laptop' to 'Always on' ... and guess what? only 10% CPU usage at bar 42.
I was running on batteries using the build-in soundcard... I am happy now
