RTLinux Boasts Single-Digit uSec Responsiveness

An anonymous reader writes "A Linux implementation delivering single-digit microsecond responsiveness on 64-bit dual-core AMD Opteron processors is being demonstrated at the Embedded Systems Conference in Boston this week. From the article: "According to FSMLabs, an AMD Opteron 265 dual-core system running RTLinux can deliver guaranteed interrupt latencies of no more than five microseconds, with scheduling jitter of no more than eight microseconds, even with Linux under a heavy load." Heck, with numbers like that it seems like Linux could run circles around XP Pro for audio/video apps such as streaming, recording, and playback!"

Yes, but where are teh feature richs audio/video apps that are available on WinXP?

Vanilla 2.6

I think vanilla 2.6 is great when it comes to responsiveness (not counting microseconds though). I Even though I have world of warcraft eating 100% CPU in a window the overall responsiveness of the desktop environment doesn't change. same goes if you decide to start up 5 simultaneously playing movies in mplayer. Way better than 2.4 ever was.

Already Speedy

Icecast on Debian Linux already has great performance for streaming, if not "realtime" interrupts . But I do wonder about loads people have seen with standard datacenter server HW. For example, how many 128Kbps streams can a P4/4.3GHz/128K-cache/512MB-RAM Icecast2 server stream from the local filesystem (preencoded to 128Kbps MP3) to a 100Mbps ethernet, if that's all it's running under the Debian v2.6.10-5-686 kernel/OS?
