[VmWare] Reduce guest swapping

VmWare allows you to specify how the guest system handles swapping to the host disk. Much like Linux's swappiness value, you can suggest to use more host memory instead of swapping to disk; this is especially useful if you do not have a swap partition.

To edit the setting, open your VM's .vmx file, while the VM is powered off, using text editor and add these lines:

MemTrimRate = "0"
mainMem.useNamedFile = "FALSE"
sched.mem.pshare.enable = "FALSE"
prefvmx.useRecommendedLockedMemSize = "TRUE"

Note: If you are using a Linux host, use the following entry instead of mainMem.useNamedFile which only applies to Windows hosts:

mainmem.backing = "swap"
