Yes, I most emphatically do disagree with Victor! IRIX is used for mission-critical audio applications - recording as well playback - and other low-latency applications. The same OS scales to large numbers of CPUs. And it has the best desktop interactive response of any OS I've used. I will be very happy when Linux is as good in all these areas, and I'm working hard to achieve this goal with negligible impact on the current Linux "sweet-spot" applications such as web serving.

I agree. I'm not wedded to any particular design - I just want a low-latency Linux by whatever is the best way of achieving that. However, I am hearing Victor say that we shouldn't try to make Linux itself low-latency, we should just use his so-called "RTLinux" environment for low-latency tasks. RTLinux is not Linux, it is a separate environment with a separate, limited set of APIs. You can't run XMMS, or any other existing Linux audio app in RTLinux. I want a low-latency Linux, not just another RTOS living parasitically alongside Linux.
