Linux 2.2 and 2.4 VM Systems Compared

Posted by CmdrTaco on from the hey-look-someone-did-actual-tests dept.

Derek Glidden writes "I got sick of trying to figure out from other people's reports whether or not the 2.4 kernel VM system was broken or not, so I decided to run my own tests, write them up and post them online. The short conclusion is that the 2.4 VM rocks when compared with 2.2, but there's more to it than just that."

    Can you imagine a beowulf cluster of linux 2.2 and 2.4 virtual memories?

    Thank you.

  3. *BSD-is-dying-posting is dying. by Anonymous Coward · · Score: -1, Offtopic

    Yet another crippling bombshell hit the beleaguered *BSD-is-dying-posting community when last month IDC confirmed that *BSD-is-dying-posting accounts for less than a fraction of 1 percent of all troll posting. Coming on the heels of the latest Netcraft survey which plainly states that *BSD-is-dying-posting has lost more trolling share, this news serves to reinforce what we've known all along. *BSD-is-dying-posting is collapsing in complete disarray, as further exemplified by failing dead last in the recent Sys Admin comprehensive networking test.

    You don't need to be a Kreskin to predict *BSD-is-dying-posting's future. The hand writing is on the wall: *BSD-is-dying-posting faces a bleak future. In fact there won't be any future at all for *BSD-is-dying-posting because *BSD-is-dying-posting is dying. Things are looking very bad for *BSD-is-dying-posting. As many of us are already aware, *BSD-is-dying-posting continues to lose trolling share. Red ink flows like a river of blood. *BSD-is-dying-posting is the most endangered recurrent troll postings of them all.

    Let's keep to the facts and look at the numbers.
    *BSD-is-dying-posting leader Benny "Stupid Trolling Retard" McGoatfucker states that there are 7000 *BSD-is-dying-posters. How many *BSD-is-dying-posters are there? Let's see. The number of *BSD-is-dying-posting versus Imagine-a-Beowulf-cluster posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 *BSD-is-dying-posting users. Goatse.cx-link posts on Usenet are about half of the volume of *BSD-is-dying posts. Therefore there are about 700 posters of Goatse.cx links. A recent article put *BSD-is-dying-posting at about 80 percent of the idiotic trolling posts. Therefore there are (7000+1400+700)*4 = 36400 *BSD-is-dying-posters. This is consistent with the number of *BSD-is-dying Usenet posts.

    Due to the troubles of Walnut Creek, abysmal sales and so on, *BSD-is-dying-posting went out of business and was taken over by Klerck who post other idiotic trolls. Now Klerck is also dead, his smelling corpse turned over to another charnel house.

    All major surveys show that *BSD-is-dying-posting has steadily declined in trolling share.
    *BSD-is-dying-posting is very sick and its long term survival prospects are very dim. If *BSD-is-dying-posting is to survive at all it will be among no life redneck retards. *BSD-is-dying-posting continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, *BSD-is-dying-posting is dead.

  4. why does slashdot temporarily ban people by Anonymous Coward · · Score: -1, Offtopic

    ...who make only TWO low-moderated posts in a few minutes. What is that about? One thing is stopping DoS attacks from people who make, say, 10 or more rubbish posts in 5 minutes, but isn't there something off about silencing people who don't think like the majority?

    I guess even Slashdot only likes free speech when the speech agrees with it (its regulars, whatever). Ah well, bunch of hypocrites.

      Liberals tend to be that way. Conservatives too, now that I think about it.

    It's not incompetant -- it's paranoid. It's intentionally paranoid to draw attention to a political issue that AC cares about.

    I don't think most people really thought the 2.4 VM was a worse performer than 2.2, especially under normal load, and in recent kernels even under high loads.

    well, I would like to say I hate the 2.4 VM. my Suse box was chuging along, and not doing anything at all, I go to the store realy quick to grab some stuff for my wife and when I return the machine is grinding like mad. I had no processes running no application up but the box was slow as hell. the light on the HDD would not turn off at all. I had to do a hard boot even after I tried to kill X since the action was taking forever.

    I have used linux for 3 years now and I have never had to hard boot it, at least not in a situation where I didn't mess up the box :-)
    3 years and one hard boot is pretty good, but it should not happen at all. I truly think that the 2.4 VM sucks and I am realy hoping that the 2.4.14pre7 VM is the goldenchild......please Linus, for 2.5 make sure the VM works before you put out 2.6, even if it takes you 2 years....oh wait :-)
