Ok for some reason I just tried it again and got a load of 19%

1) 28 -31%
2) PowerMac G5 2*2
3) 10.3.5
4) G5 2*2 Ghz
5) 1,5 Gb PC3200U-30330
6) M-Audio Firewire 410
7) don't know

1) 37% (averaged around 33%)
2) Gericom Smart Power Notebook
3) Windows XP Home (SP1)
4) P4 3.05GHz HT (Desktop Replacement) 512Kb L2
5) 1024MB Ram, DDR-SDRAM PC-2700
6) Edirol FA-101
7) 4200rpm HD (I think)

A bit disappointing...

I previously wrote:1) 28%, peaks at 29%
2) IBM thinkpad r40 laptop
3) WinXP Pro SP1 - came with the computer.
4) Pentium M 1,5 gHz
5) 256 megs of ram
6) Built-in Soundmax soundcard on Asio4All drivers
7) Don't know the hard disk Drive Speed...

Now, having upgraded to 4.03 and XPsp2, I'm actually getting better performance on this test.
25/26% average, peaks at 27%. Not a big difference, but those extra few percent might help in a live situation...

Is your edirol running on USB or FireWire?

hey man, fa101 is firewire only!!!!

but maybe thats causing troubles, who knows...
i think that firewire and usb both use cpu a lot....
for example, my pci soundcard (dsp24 mkii from staudio) doesn´t need any cpu (as shown in task manager - performance)

There is a difference between the cpu usage shown in ableton and the task manager - Performance!

task manager also takes into account drain on the cpu from ableton's video rendering. the Live meter is measuring drain from the audio engine.

1) 137% (90% impluse alone ; 75% simpler alone) @ 524 samples buffer
2) G3 powerbook / pismo (version=83)
3) OSX 10.2.8
4) 500mhz 1mb level2 cache
5) 384mb ram /dunno speed of ram
6) Hammerfall pcmcia multiface
7) Fujitsu MHK2120AT 12gb 4200 rpm

Have you tried running the test on your onboard soundcard? I'm looking into purchasing a solution with multiple outs, so i'm really curious about what's eating cpu cycles. I'm extremely happy (and surprised) by the onboard soundcard on my HP nx7010 - but i don't want to introduce MORE cpu usage by using another solution for the sound

iMac G5!!
just got back from the store, ran some tests with the Live 4.03 Demo, here's what I got:

1.) 37% Peak, jumping wildly between 33-36% most of the time
2.) iMac G5
3.) Mac OS X 10.3.5 (IIRC)
4.) 1.6GHz PowerPC G5, 533 MHz bus speed
5.) 256+512 MB RAM PC3200 (400MHz)
6.) built-in audio
7.) stock 80GB HD, 7200 I guess

If performance scales linearly just as it does with the PowerMacs, the peak should come down to 33% on the 1.8GHz model. I had to run the tests in a regular user/visitor account, so I couldn't just kill any weird processes I didn't need (got rid of HP scanjet background stuff, ichat service, ical service, some modemOnHold stuff), but I asked the shop guy/admin to set CPU to maximum in the energy settings before I ran the test mutiple times.
The G5 is supposed to access RAM more efficiently when two DIMMs are used (128 bit vs. 64 bit access?) as it was the case in this machine, but I never got round to actually test this. Does it really make a difference?

So, what's your verdict? Worth the money for using it with Live or not?

thanks for testing the iMac G5!
