Are you talking about a new kernel or a new userspace? It's an important distinction.

- jacquesm 14y agoI'd be very happy to see something like QnX, unix on the outside, robust message passing kernel with clustering built into the heart. QnX is much more than just a neat little kernel to do embedded stuff with.
- spc476 14y agoI remember working with QnX back in the mid-90s and found it quite fun (compared to Unix at the time). A friend of mine worked at a company that made commercial X servers and that company's fastest X server ran on QnX (yes, even with the overhead of message passing, it was faster than their Unix version on the same hardware).
- jacquesm 14y agoHummingbird by any chance?
- spc476 14y agoNo, it was Metro-X from MetroLink.
- jacquesm 14y agoThat vaguely rings a bell but I don't think I've seen it in action. Pity! Maybe the future will bring us something like that again, I sure wouldn't mind. The nay-sayers argument that 'micro kernels are slow' seems to be mostly limited to those that have never actually used a micro-kernel based OS for anything. What I remember was - for the time especially - nothing short of astounding performance, 30K slices / second on a lousy 486/33 was not exceptional at all. At the time most other OSs were doing 20 or so...
