    Default Too **** slow

    Hi all,

    I'm on openSuse 13.01, KDE. The problem is that it all gets sloooooow after I use Internet (I use both Mozilla Firefox and Chromium). When these two browsers are open, everything works sooo slow. I have enough memory, I don't know what's eating it so much. Any ideas? Thank you.

    Please define "enough" - your definition and the definition that others
    use may not be the same - specificity is everyone's friend here.

    Thanks. Then you have _little_ memory, just under 2 gibibytes. And, your
    swap is also too small, about the same size.

    I would increase swap to about 10 GB.

    The top banner of "top" would have been interesting to see, you removed it.


    Well, both firefox and chromium use lots of memory, and you do not have
    lots. System probably uses swap then, and that is slow. Also, having
    little memory means that the system can not dedicate enough ram to
    buffers and disc cache.

    2gb is on the (very) low side for running a modern operating system. I'd at least double it, but 6gb or 8gb would be better - especially if running a full featured desktop like KDE or Gnome.
    I'm not sure I'd agree with robin_listas that 2gb of swap is too small. If you have sufficient physical memory then a 2gb swap should be fine.

    You can have swap as big as you want. As 2 GB of RAM is to little, he
    needs more swap instead.

    Of course, adding more RAM is preferable - if possible and feasible.

    Yes, of course. The less RAM you run, the more space you will require for Swap.

    And there is never too much Swap, other than it wastes disk space if it is not getting used. This is only of concern to people with limited drive space.

    His output shows zero swap. used. But it is not certain the figure comes when the browser is running. 2 gig should be ok for most things unless he has a bunch of tabs open
