VMware Guest VM Performance Enhancing June 14, 2009

Here are a few parameters that I have come across that others are using to increase their VMs performance. Update your .vmx file with the following settings:

See this site for further configuration explanations: http://sanbarrow.com/vmx/vmx-config-ini.html

sched.mem.pshare.enable = "FALSE"
mainMem.useNamedFile = "FALSE"
MemTrimRate = "0"
MemAllowAutoScaleDown = "FALSE"

Finding what settings in the .vmx file actually do is pretty vague but from my searches here is what I found.

sched.mem.pshare.enable = "FALSE"
This disables page sharing. Disable this if the Host has enough memory. This should improve disk I/O on slow disks.

mainMem.useNamedFile = "FALSE"
This one stops the VM from using the memory file for swapping

MemTrimRate = "0"
This stops the Host from taking back memory space that the VM is not using

———————
The ones that I put into use are:
sched.mem.pshare.enable = "FALSE"
mainMem.useNamedFile = "FALSE"
