I should have said: without rtirq the setup is not really usable for
professional sound-production or live-performance, but handy nonetheless.
> really? how so?
because you can not guarantee that soundcard I/O is handled in time.
you might just as well run a lowlatency kernel without RT.

The general I/O performance may even go down; since fi. the sound-card
would be allowed to /interrupt/ network-i/o. - In >99% of cases the
system will run without RTirq as it will with RTirq.
If we reach a more stable 2.6.26-rt - we should ask the PPL on
ardour-users ; some of them do 64 or 128 audio-channels and you will
definitely experience a difference there.

heh, hints are hard to come by.
most of the time I run at 64 * 3 (for recording) and 1024 or 2048 (for
mastering); mobile via USB, if I need more channels via 1394. The
build-in HDA on this TP-X60s does only "work" at 128, 1024 and up, but
that's OT; i mostly use it only as "phone". - I use max. 10
hardware-channels, but occasionally go above 256 jack ports.
I never succeeded to get a Xrun free setup without rtIRQ - but the hdsp
multiface PCI/PCMCIA interface may be more /forgiving/ that the USB or
