Was still suffering from major performance problems using a variety of VMs on VMware Workstation 5.5.3 and VMware Server 1.0.1 ( using VMs created for Windows Server 2003 and Windows 2000 Professional ).
In all cases, the overall responsiveness of the VM was absolutely abysmal, even when running with 2 GB ( in the VM ) on an 8-way server with 16 GB RAM ( running W2K3 as a host OS ).
After some serious Googling, it turned out to be a setting in the .vmx file ( same directory as the actual VM image ).
Simply by adding: -
mainMem.useNamedFile = "FALSE"
and physically restarting the VM ( actually shutting down the guest OS, and stopping/starting the VMware session ), the performance seemed to improve drastically.
This, combined with VMware Converter ( as blogg'd about previously ) allowed me to take a demo deployed on a native WinXP OS, convert it to a VM and then run it as a guest on the same machine that used to host it full-time.
As far as I can establish, this setting prevents the guest OS from paging its memory back to the host OS' disk. What's wierd is that I'd allocated 2+ GB to the VM, and Task Mangler didn't imply that memory was short but ..................
Remember kids, ymmv

Geeking in technology since 1985, with IBM Development, focused upon Docker and Kubernetes on the IBM Z LinuxONE platform In the words of Dr Cathy Ryan, "If you don't write it down, it never happened". To paraphrase one of my clients, "Every day is a school day". I do, I learn, I share. The postings on this site are my own and don’t necessarily represent IBM’s positions, strategies or opinions.
