Good afternoon,

The last time I ran VMWare with this laptop was under KDE 3 and Gutsy and
was able to run multiple 1 GIG VMs without a problem.  The install was a
fresh install of Kubuntu 8.04 Remix with nothing other then the packages
needed to install VMWare Workstation and get it to install.  Since I have
wiped Kubuntu and gone back to a more stable version of Vista, I cannot tell
exactly what processes were running other then what I would consider
"normal" processes.

The question still stands:  Does KDE4 consume more resources then KDE3?

I know I can tweak a lot things based on the links you provided, but I don't
have the time to spend trying scripts and other changes, when it works fresh
out the box with Vista.

Note I really enjoy KDE4, I use it through VMWare full time on my work
machine, but just can't deal with VM's crashing and being unstable under
Kubuntu.
