Non-Deathmatch: Preempt v. Low-Latency Patch

Posted by timothy on from the floor-wax-and-dessert-topping dept.

LiquidPC writes: "In this whitepaper on Linux Scheduler Latency, Clark Williams of Red Hat compares the performance of two popular ways to improve kernel Linux preemption latency -- the preemption patch pioneered by MontaVista and the low-latency patch pioneered by Ingo Molnar -- and discovers that the best approach might be a combination of both."

  1. I preempted the current Linux kernel by Anonymous Coward · · Score: -1, Flamebait

    on my home system.

    It runs better now that I've installed the NT kernel.

    This is why I love open source software. Linux will push ahead as Windows is left in the dust.

    • Yeah, because we've really seen that thus far....

    HAHA, you are stupid n00b. You don't know shit about Linux or computers, you dumb fuck. You think people here will help you? Bullshit, look you already got a (-1). I'm posting anonymously because I will get one too and I don't want to hurt my karma, but you goddamn you are dumb and you will never get Linux. Hahahahahhaha, you suck.

    Ohh yeah.. I forgot to tell you. Fsck IE. Any fucktard that uses slow ass IE when Opera is available is a fucking moron.

    And it doesn't surprise me at all that 95% of desktop users are morons. Hell, you probably use IE, and you chose Archie Bunker as a nick. You MUST be a moron. Thanks for speaking up for your species. Now please sit down and let the IQ-enabled people talk.

  8. Re:Measuring latencies? by Anonymous Coward · · Score: -1, Flamebait

    Here's a question. How do you go about doing fine grained measurements of these latencies? Every time I've tried doing timings with Linux I've had problems being able to get accurate, fine grained results.

    That's an excellent question. I'm glad you asked. The way you measure low latencies is to stick a thermometer up your ass and measure the amount of time (the latency) it takes for you to jump.
