Speed Up SMVI/VMware Snapshots

I found that there is a big improvement when running SMVI and selecting the VMware Snapshots option on NFS datastores after adding the following to /etc/vmware/config and rebooting the host:

prefvmx.consolidateDeleteNFSLocks  = “TRUE”

You will know whether it is working because you will see a .lck file appear in the folder containing the vmx file and snapshots should be opened and closed more quickly (try opening a ping to the VM being snapshotted and see if you lose fewer after making the change).

    Does this apply to vSphere 4.1 as well? I couldn’t find anything conclusive on VMware’s KB.

    Thanks in advance.

      This does not apply to vSphere 4.1 as this option is now deprecated and does not have any impact when made.

      VMware confirmed this to me very recently after we saw no change during testing.
