Insert the following code into the *.VMX file:

sched.mem.pshare.enable = "FALSE"
mainMem.useNamedFile = "FALSE"
prefvmx.minVmMemPct = "100"
prefvmx.useRecommendedLockedMemSize = "TRUE"
mainMem.partialLazySave = "FALSE"
mainMem.partialLazyRestore = "FALSE"
priority.grabbed = "high"
priority.ungrabbed = "normal"
  • sched.mem.pshare.enable = "FALSE", by disabling memory sharing your guests will not share common memory blocks. Your VMware product will also stop comparing memory blocks
  • mainMem.useNamedFile = "FALSE", doesn't use named-file - use for VMs on USB-disks or other slow disks. On Windows: useNamedFile= "FALSE" causes memory to be backed by the host's swap space.
  • prefvmx.minVmMemPct = "100", fit memory into RAM. Whenever possible, avoid settings lower 100%.
  • MemTrimRate = "0" , by disabling MemTrimRate, memory allocation inside the guest is faster because it doesn't take and give memory to the host os upon all requests.
  • prefvmx.useRecommendedLockedMemSize = "TRUE" , this tells VMWare whether to use a fixed sized memory chunk or balloon and shrink memory as needed.
  • mainMem.partialLazySave = "FALSE" , do not take snapshots in background
  • mainMem.partialLazyRestore = "FALSE" , do not restore snapshots in background
  • priority.grabbed = "high" , sets the priority for the VM in grabbed state
  • priority.ungrabbed = "normal" , sets the priority for the VM in ungrabbed state.
