[kde-solaris] swap space requirements [was: KDE 3.1.4 - Can'ttalk to klauncher]

[Rolf Sponsel]

Best Stefan,

I really don't want to argue with you, but
your experiences are different to mine, and
I cannot find any support for your "rule of
thumbs" in the Solaris documentation either. :-(

http://docs.sun.com/db/doc/817-2874/6migoiaaj?q=swap&a=view
docs.sun.com: System Administration Guide: Basic Administration

Have a look under the title "Planning for Swap Space".


Best Regards / Rolf

BTW, I'm running GNOME 2.2 on Solaris 7
      on a SPARCstation 5 with 128 MB and
      512 MB Disk Swap quite acceptable.
    ( the factor 4 here :-) accidentally
      corresponds to what you recommend
      mainly because I need that much when
      compiling H323 software ). -Not bad.
