There are two key best practices about VMware VM Windows page files (swap files).
I’ve found for optimum performance, it’s best to allow Windows to manage the page file. (see illustration)
I’ve also found it’s best to configure ESX to store the page files in a shared data-store so when VMs are vMotioned the page file is not copied to the new location. This reduces time during the vMotion process. Read about VMware SWAP File.

This is also a VMware Health Check best practice.
