    Phoronix: Benchmarking The Ubuntu "Low-Jitter" Linux Kernel

    There's an independently maintained "low-jitter" version of the Linux kernel targeting Ubuntu, which claims to be faster, but is that really the case?..

    This article measured jitter in the most false way possible. Maybe this is a better approach?

    You must really think that Xeon cpus are different than i7. For your purpose, get i5-3570K, GTX 660/670, 8 GB ram (or 16 as it is cheap anyway). I use i7-3770S, but i did not buy it, if i would need to pay for it it then would have been the i5-3570K or i7-3770K. S is really stupid for oc tests.

    A quad core with 1.8 ghz is totally underpowered. Thats a server cpu where you could add 2 of em onto 1 board.

    Did you really look at the system you specified here:

    http://paradoxuncreated.com/Blog/wordpress/?p=3866

    Then take a look there:

    The E5-2603 is without any Turbo, you are stuck with 1800 mhz! Has absolutely nothing to do with low latency! Of course for somebody like you this must sound fine. For gamers the per core speed is important and that for 3-4 cores mainly (for games). A GTX 670 would be a better fit for (win) gamers, on Linux there is only Heaven benchmark - you can forget Oilrush.

    Only a complete idiot would buy a cpu with 1.8 ghz base clock and s2011 -also e5-2 means that you can combine 2 cpus, e5-1 would be for 1 socket. i7-3770k/i5-3570k on z77 is the way to go for gamers. That only showed how incompetent you are.

    What were the responses to his posting on the rt-user list? I take it they were all dumbfounded by his genius.
    he's not a real muslim. He has a identity crisis most likely (i would guess). I have a few friends whom are muslims and they would have ZERO respect for this guy, and you are correct he isn't supposed to talk the way he does. As far as a state of insanity - i think to some degree he does have mental problems (just based on his posts) - but i'm no doctor. lol.

    As far as his posts elsewhere.;
    https://www.google.ca/search?q=Uways...irefox-nightly

    his posts on Linux-rt-user-list look to be cross-posted from LKML so it's easier to just google his real name + lkml (or + rt-linux-user).

    some of his LKML ones are pretty funny too ~ like when he was told subjectivity doesn't cut it and that he needed to provide some data to support his claims...lol

    bahahaha. what a dumb ass you are, paradox.

    Don't worry NomadDemon. Paradox may talk about us being the ones sitting in our own piss and shit. But in this picture (real picture of Paradox), he clearly has shit all over his clothes (especially the shoulder) and lives in an absolute dump;



    So i highly doubt he should be talking about anyone else' piss and shit, when clearly he has no concept of cleanliness. I mean look at him ~ who would actually take this fucking retard seriously... Should anyone consider his thoughts on sexuality? nope. What does he know of such things? (probably nothing). Lessons on morality? read a handful of his comments and the answer is certainly no. get lessons on tuning the linux kernel from him?? nope. The guy doesn't even know how/where the logging info he needs is, yet i'm to rely on his 'expertise' for tuning a kernel? fuck no.

    regardless, he has no substance, nor the expertise he claims to have over all others. He is unable to backup anything he says and from observing his behavior elsewhere online (various lists, etc) I don't think anyone else finds anything he has to say all that insightful / useful either.

    I foresee no one actually using his kernel, nor do i see it becoming popular or even as something unique or useful in any way. I think it is more likely that he is kicking a dead cat (his piece of shit core2duo) trying to get that tiny last bit of performance out of it, while also at the same time vacationing in placebo land

He is the only person i know of that has "PRAISED BE GOD" written in the README's for his crappy plugins - which is odd to say the least. He's heretic even in his own faith (proven to be in another thread), he's just lucky he's a convert and not living in an islamic state.

    And by the way, Liam is most certainly correct -> RT can affect throughput negatively, this is a well documented FACT.

    I find it laughable that in the other thread (where PU and i got into an argument) he claimed that his 'low-jitter' kernel essentially made RT useless/not needed anymore, yet now a week or so later he plans to be his kernel using the RT patchset. lol. Even funnier, him posting on the rt-user-list;

    i know what jitter is and i wnt to fight it, even with cost of maximal performance.

    learn to read man...

    problem with you is "everyone are idiots i know the hiden truth"

    the mothod you use to talk is so primitive...
