Thread: 64 bit for 4GB Ram

  1. #1

    Question 64 bit for 4GB Ram

    Hello everyone.
    I have 4 GB of ram from witch the Video card takes also some, does it worth to use 64b edition of openSuse ?

    Or the 32 Bit is enough , and will see all amount of ram ( Maybe using PAE kernel )

    Any suggestions ?

    Default Απ: 64 bit for 4GB Ram

    In my opinion is better 64 bit version, beacause 64 bit operating systems exploit all hardware and of course you have better performance.

    The 32bit pae or desktop kernel would be enough to support the 4 GB, but the
    64bit will probably bring you an additional performance boost.

    Just remember, when installing some third party programs (like Skype) you
    may need some additional 32bit libraries.

    Yeahh he is right. Because these libraries are not 64bit, you need to install them in their 32bit form.

    I already noticed this, but i always wonder, installing 32 bit libraries does not hurt performance ?
    I mean i feel like i do something wrong everytime i install a 32 bit lib, dont ask why, i just feel is not right

    Look you can install 32bit libraries.

    No it's ok.

    I have 64 bit system with 32 bit libraries and programmes.

    Do not worry everything is ok. I do not want for you to have stress.

    Question Re: Απ: Re: Απ: Re: 64 bit for 4GB Ram

    In my experience it makes no big difference if you are performing normal desktop tasks whether you use 32 bit or 64 bit on a normal 2 core cpu with recent hardware.
    The 32 bit / 32 PAE / 64 bit problematic gets interesting when you go beyond 4 GB. This difference will be more visible the more applications you try to run instantaneously on the same machine as an instance.
    A lot depends on your hard and software when you decide. Note that:
    • applications that monolithically attribute memory space (like STATA did - do not know if this is still the case with the recent version)
    • image editing and video editing
    • databases

    should profit a lot from the 64 bit, provided they are native 64 bit programs. If you run only 32 bit programs in 64 bit, in emulation you will have no advantage.
    Some programs (like matlab accademcial version, available only in 32 bit) have trouble running well in "32 emulation" and are more effective in 32 bit environment.
    If this helps you: apparently this is the first time that the 64 bit version has less problems then the 32 bit OpenSUSE (in my experience for years it was the other way round) and therefore you should maybe opt for 64.
    Last but not least you will have the security that you invest in the future with 64 bit. It is a question of time that 32 bit hardware will die out. Even the most recent netbooks tend to be again 64 bit capable if I am not in error (recent Atoms dual core). You cannot run the 64 bit version of a commercial software in 32 bit, but often it is no problem to run 32 bit in 64 bit. As licenses are often different for these versions, using 64 bit will protect your investments for the near future without (in the majority of cases) making you loose your existing assets.

    32 bit vs PAE. This is not any more a decision since AFAIK all 32 bit kernel of SUSE are now PAE. But PAE, although it allows to address the space above 4 GB is not a good solution if you need memory space for the application itself as this space will not be addressable to the 32bit applications but only to the OS itself.

    Hope that helps in the decision.

    Depends on what you use.

    Running at 64 bits doesn't automatically means "faster". What it means is
    "larger". Compare a road truck, with a double truck, both at the same
    speed: the double carries double the load. If you have to move more data,
    like databases, video conversion, etc, it should "run" faster (it doesn't
    mean "it will"). It also means that the memory buses may have to move
    double the data, and it "might" not cope.

    For example, suppose a program needs to count a loop a thousand times, so
    you use an integer, to say, invert an array of integers. Now you compile
    the program for 64 bit, and the variables are made double size - what for?
    There is no need. It will actually run slower having to read all that extra
    data from memory, unless the memory can feed that data at the same speed...
    At best, it will run at the same speed.

    There would be a gain if the original program had to invert an array of 64
    bit integers, because for the 64 bit it is only one op.

    It should see all your 4 GiB memory, without needing PAE (for that reason,
    there are others).
