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!"

I said it before, I'll say it again, hacking a realtime scheduler into Linux does not a realtime OS make. The hoops you have to jump through to make RTLinux perform means you can't possibly put it on the desktop. Building embedded systems where you get to control the hardware configuration 100% and then touting how lean and mean you've made it is all well and good, but it means nothing for the rest of us using commodity hardware.
