    Increasing performance

    Hi guys. I have a Windows OS to which I installed kubuntu. If I remember correctly, upon installation, it asked how much space I should allocate to it, and I selected the maximum available. I am running some quite intensive tasks on kubuntu, so I was wondering if there was anyway to increase this further (the tasks is running a virtual world I have programmed, so very memory intensive). At the moment, I can work ok with the virtual world, it is just a bit slow at times. I would like to see if I can basically give kubuntu my full power, as if its my only OS (And if this is an option, what would happen if I then tried to run windows afterwards?).

    Cheers

    Nick

    Re: Increasing performance

    When you are booted into either Kubutu or Windows, that OS is the only OS running, unless you are using Vmware or Virtualbox to run on OS inside the other.

    Now to help, you may want to disable any desktop effects you have running, which can cause some slowness of the graphical stuff. But really, ram is where it is at.

    How much ram do you have, how fast is your cpu, what graphics card do you use, and what software are you running for your virtual world? that info would give us a start for any recommendations for you.

      Re: Increasing performance

      Sounds a little like you're confusing "space" with "power"

      Power comes from CPU, GPU, RAM etc.

      Space is how much hard drive space you allocated to the install.

      So are you asking for more memory and CPU power or more hard drive space?

        This sounds to me like you installed it via Virtual Machine. This means that you are running Kubuntu inside Windows, which means that not only is Windows running and taking up 'x' amount of RAM, but Kubuntu is also running, taking up 'y' amount of RAM. At times, it'll work fine, but if either Windows or Kubuntu start to take up more RAM then your total system provides, it'll slow up.

        Just my observations, maybe someone, as well as the OP, can use this insight to come to a good conclusion.

          Hi guys. I dont think I installed inside a VM. When I boot up I choose between Windows and Linux. So from your comments, I would say I am after more power. I am using a 64 bit machine, 4gb ram, intel core. Not too sure on the other specs. In terms of the virtual world, it is something I have programmed myself, and it consist of thousands of classes. It runs using java, and java related servers. It wont work on Windows under a 64 bit JVM, but running it with a 32 bit JVM it runs really well. Within Linux, I assume its using 64 bits, but the performance seems less that in 32 bits windows. Its nothing major, like when I click on a menu item, it takes a second to display etc. If the world is over populated with models aswell, it may have difficulties displaying everything. I was thinking they may be something I could do my end within Linux to make things slightly faster.

          On a side note, is ubuntu, kubuntu, linux etc all the same thing?

          Cheers

            Java, well that might be a slow point
            Whether you have 32 or 64 bits depends on what you installed - linux distros usually offer installation images for both.

            If you open a terminal (Konsole in Kubuntu) and enter this command
            Code:
            uname -a
            you will get some kernel version info. If you see something with 'x86_64' you have 64 bit, otherwise you have 32 bit.

            I am not a programmer, so i cannot comment on java other than i have always found it slow no matter the OS :/ but I am also unsure that you will bet more 'performance' with 32 or 64 bit. There probably are code optimizations you can make to the code to improve performance in Linux, and there are also different java virtual machines you can use (more than 1 can be installed in Linux at the same time.)

            Anyway, Think of ubuntu/kubuntu, Fedora, Suse, et all, as different variants of linux. So in many ways they are the same, but are also quite different.
