VMware Server Disk Performance Tuning (Example)

I found my VMware Server (Version 1.09) Linux Host running very slow when one of the guest OS doing backup.

Whole system is not responding while doing backup. This made me crazy for long time.

Yesterday, I tried to do some research about Disk Performance tuning.

Finally, I tried these settings and it works for my VMware Server Linux Box.

You can open the configuration file *.vmx and add the following lines to the configuration file.

# VMware Disk Performance tuning
mainMem.useNamedFile = "FALSE"
sched.mem.pshare.enable = "FALSE"
MemTrimRate = "0"

Wow, after adding it. Performance improved a lot :) . (Don’t ask me for the figure). I am lazy to do benchmark.
