Performance Tests:

PC: AMD Duron 1800 (64kb cache: too low!), 384mb RAM, HD 30GB IDE 7200 RPM,
Soundcard: SB Live! So: cheap hardware! Not good for this things, but, see:

Distro: Live-CD Musix GNU/Linux 1.0-r0b3

Linux Musix 2.6.21 #1 SMP PREEMPT Fri Apr 27 18:08:33 EEST 2007 i686 GNU/Linux

Desktop: Icewm + Rox-Filer (Musix's default)

Ardour 0.99.3

Recording to HD (IDE, 7200 RMP)

I am not using plugins (LADSPA)

-----------------------------------

JACK: 5.3 ms latency, 48khz

20 mono tracks: I can play or record 20 mono tracks without problems at all,
no xruns, no stop.

-----------------------------------

JACK: 2.7 ms latency, 48khz

20 mono tracks: I can play or record 20 mono tracks without problems at all,
no xruns, no stop.

------------

Less latency: my SB Live! does not allow me to lower the latency less than
2.7ms when JACK is in Duplex mode, but I can lower it if I choose only
playback from the qjackctl setup.

----------------------------------------

JACK: 42,7 ms latency, 48khz

39 mono tracks into Ardour: OK, no xruns... sometimes Ardour stop and
says "your machine is not fast enought...etc", but it happends when I move
some slider into Ardour or something like this. If I just record or play,
there are no problems.
