Thread: Opensuse too slow on 512MB-1GB RAM and 2.4GHZ processor system

    Default Opensuse too slow on 512MB-1GB RAM and 2.4GHZ processor system

    Hello,

    I hv installed opensuse on a more then 50 systems with rams 512MB-1GB and processor 2.4GHz, 2.8Ghz core2duo HT ,etc. The problem is that opensuse runs very slow. It takes alot of time to open Libre office and if you run 3-4 programs at one time, the system tends to hang. I hv both installed Gnome N KDE, no multimedia and games. Print server, Network Server and remote server

    512MB - 1GB is not enough RAM to get fast performance out of KDE nor Gnome. You could try to tune the desktops for more speed, but that could be a lot of work for 50 systems: KDE is slow – for dummies

    If your users can live with a less shiny desktop, then I recommend the LXDE desktop which is quicker with that small amount of RAM.

    xfce is also enough fast for this and has a better interface (in my opinion).

    Indeed the 'imho' is the operative word. I prefer LXDE (which has a more conventional - some would say a more simple/bland appearance). LXDE also has a smaller memory foot print than XFCE, (and smaller than Gnome, and smaller than KDE), and hence I believe it to be faster on older hardware than XFCE (but NOT faster on newer hardware).

    I've seen one recent post that noted the memory footprint of XFCE to be larger than that of Gnome.

    Still, I know other users who prefer XFCE.

    As noted, it all boils down to one's opinion.

    Very little memory. You will need swap, and you don't mention how much you
    have. Else, crash.

    LO uses a huge amount of memory. Mine is using a virtual amount of 3 GiB.
    About 300 MiB RES.

    Gnome and KDE both use lots of memory.

    No wonder your machine is slow.

    Hi,

    With 512MB of RAM I would expect some slowness. I run KDE on an EeePC 900 which has a slow, 900MHz, CPU and 1GB of RAM - quite successfully.

    I have allocated a 1.5GB swap partition (1GB for hibernate and 512MB for general swap use) and I often use Firefox and LibreOffice for everyday tasks. I do not run services on this machine, so that might be a factor in the poor response you are seeing.

    You need to identify in detail what processes or settings affect your system
    performance to tune it. In principle I can second the comment from
    neildarlow, my own experience is with an old 1800 MHz 512 MB machine and
    openSUSE 11.4 Gnome 2.32 that it runs just fine and an Amilo 1703 laptop
    with 896 MB running 11.4 with KDE 4.6 also working smooth.
    So there is something on your system which needs to be tuned (no surprise
    for a low resource system that the defaults from a standard installation
    which are set for more modern and powerfull systems are not the best here).

    First things to look at: Run "top", are there file indexers running in the
    background, are there some suspicious processes consuming a lot of memory or
    cpu cycles or causin heavy I/O which you do not really need?

    Consult the tuning guide to understand how to diagnose your system and which
    tools are available:

    ???

    I use LXDE with thunderbird for mail. Note LXDE can use any app that installs on KDE and Gnome. For example I use acroread for pdf, but there are other choices. I have libre office installed. Yes it is slow but it is not that slow. Its faster than same on Gnome or KDE or XFCE. I find it faster than Microsoft Office on Windows7 on same hardware.

    What graphic driver(s) are you using. That can also make things slow.

    One thing I have also found is when I install 11.4 fresh with new .kde folder and everything, I get a lot of unecessary akonadi processes such as replicated contacts and calendars. If you go to the akonadi configuration you can delete all the duplicates and have a smaller memory footprint. I remember going from a 300mb footprint idle to as low as 160mb footprint idle. Of course turning off desktop effects and the other tricks from Oldcpu's post can also help.

    Take Care,
