Hello,<br>
<br>
Have you tried using Ubuntu with KDE3 or even with Gnome to see if you<br>
get this same behavior? How much memory does the system consumes when<br>
it startted? You can't blame KDE4 for being a memory hog if you<br>
haven't tried other approaches.<br>
<br>
One thing i know for sure is that, in Ubuntu, VMWare DOES behaves<br>
weirdly slow out-of-the-box (at least for me).<br>
I've found some tips around the net that helped me get a lot more of Vmware.<br>
Try using then and post the results back:<br>
<br>
You can tune the EXT3 partition where your VMs are to get some more<br>
performance of your disk:<br>
tune2fs -O has_journal -o journal_data_writeback /dev/hda1<br>
tune2fs -O dir_index /dev/hda1<br>
e2fsck -D /dev/hda1<br>
Put these in /etc/fstab: ",noatime,nodiratime"<br>
<br>
More tips here: <a href="http://en.opensuse.org/Speeding_up_Ext3" target="_blank">http://en.opensuse.org/Speeding_up_Ext3</a><br>
<br>
Some changes you might want to do in /etc/vmware/config<br>
prefvmx.minVmMemPct = "100"<br>
mainMem.useNamedFile = "false"<br>
mainMem.partialLazySave = "FALSE"<br>
mainMem.partialLazyRestore = "FALSE"<br>
MemTrimRate=0<br>
sched.mem.pshare.enable = "FALSE"<br>
prefvmx.useRecommendedLockedMemSize = "TRUE"<br>
<br>
More tips and explanations of a lot options here:<br>

<br>
<br>
Also, MAYBE you have some process running on Ubuntu that is doing a<br>
lot of disk access.<br>
Try monitoring it with pidstat -d 3 30, and see how is the culprid.<br>
<br>
If you still have issues after that try reporting back to see if we can help.<br>
Another good place to look for problems with VMware is the official<br>
vmware forums (<a href="http://www.vmware.com/communities/" target="_blank">http://www.vmware.com/communities/</a>).<br>

</font></blockquote></div>Good afternoon,<br><br>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.<br>
<br>The question still stands: Does KDE4 consume more resources then KDE3? <br><br>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. <br>
<br>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.<br><br><br>Jonathan<br>
