Ake je doporucenie pre Transparent page sharing pri virtualizovanych Terminal Services?

vSphere’s ability to overcommit VM memory and memory de-duplication through transparent page sharing (TPS) is highly useful for the consolidation of many VM’s on a single server, especially within Server Hosted Virtual Desktop scenario’s. Nevertheless, one of the older Terminal Server best practices floating around the internet communities was to disable TPS. Project VRC phase 1 showed that disabling
TPS improved performance by 5%. This is understandable, since TPS is possible through a background process which is scanning memory, and this consumes a modest amount of CPU. However, the performance impact of TPS was only visible with full CPU loads. TPS has no performance impact under normal conditions.
Before the update of this whitepaper, Project VRC concluded: when it is the primary objective to maximize the amount of users with TS workloads and there is enough physical memory available, it is recommended to disable TPS. However, this VRC recommendation should not be understood as an overall recommendation to disable TPS. For instance, when maximizing the amount of VM’s is the main goal (this is quite common, e.g. VDI and rather typical server consolidation efforts), TPS can be very helpful. It is important to note that VMware does not recommend disabling TPS, their publications have shown TPS does not impact performance.
