Whitepaper: VRC, VSI and Clocks Reviewed (Project VRC - Login Consultants)

Jeroen van de Kamp and Ruben Spruijt have released a new whitepaper.


"This whitepaper is a review and reflection on previous Project VRC publications, the benchmark:  "Login Virtual Session Indexer (VSI)" and Windows clock behavior within virtual machines.  This discussion is fueled by the fact that results from the individual Project VRC whitepapers are set side-by-side to compare hypervisors.  Project VRC has been in discussion with both vendors and community, and performed additional research in this context.  Before Project VRC can publish new results, it is important to address any questions, review the impact of this discussion and improve VSI where possible."


For Project VRC to move forward and publish new results, it is important to fully understand the impact of this conversation and improve the methods used where possible. In this document the following topics are addressed:


1. The Login VSI Methodology;

2. VSI 1.0 Optimal Performance Index;

3. "Stuck" Sessions;

4. Response time measurement method and clock drift;

5. Using Microsoft SQL Server 2005 as a reference clock;

6. Login VSI 2.0;

7. Reviewing Citrix XenServer and VMware vSphere 4.0;
