Swap Memory

When running gns3, my cpu is ok, but my swap memory pegs out at 100% after about 10 routers.  Anyone know how to fix that?

  • Try adding the ghostios and the sparsemem options into your .net
    file.  These should reduce the amount of RAM you need to run the
    routers.  If they don't, please post back how much RAM you have in your
    machine.  Thanks.  Here's an example:

    model
    = 3660

    ghostios
    = true

    sparsemem
    = true

  • Thanks for the tip.  I did  find a web site that helped me
    increase the swap memory, which helped for a while, but still locking up after
    about 9 or 10 routers.  My ram is 2 gigs and I increased the swap memory to 2
    gigs also.  Now, the swap memory is not maxed out but it still freezes up after
    9 or 10 routers. 

     

    I am looking at my .net file and see that sparsemem is true, but
    not ghostios.  I’ll turn that on and try it again.  Thanks again.

  • I would increase your overall memory in your machine if you can. 
    Bumping to 4GB if you can will dramatically increase your chances of
    being able to run that many.  Also are you running Windows or Linux? 
    I've never tried Windows but as I understand it Linux has much better
    performance overall.  I'm currently running Ubuntu 9.10 x64 and it's
    awesome performance wise.

  • Thanks. I'm planning on getting a new laptop with at least 4Gb, expandable to 6 or 8. I'm using ubuntu 10.04.
