Simple definition
Transparent Page Sharing can deduplicate identical memory pages on supported VMware hosts, subject to security settings.
Purpose and use
TPS, Transparent Page Sharing, reduces physical memory use by combining selected identical pages under platform rules.
How does it work?
Matching content can share a page until a write requires a separate copy.
Example and verification
Measure actual savings and verify the sharing scope permitted by security settings.
Points to watch
Cross-VM sharing is not necessarily enabled. Salting and versions affect behavior, so savings must not be assumed.
In short
TPS conditionally optimizes identical pages without increasing installed RAM.
