Server-Side Response Time Measurements

One key design choice for Login VSI tests was the decision to execute the workload directly on the target system within the session instead of using remote sessions. The scripts that simulate the workloads are performed by an engine that executes workload scripts on every target system, and they are initiated at logon in the context of the simulated user’s desktop session.

An alternative to the Login VSI method would be to generate user actions on the client side through the remoting protocol. These methods are always specific to a product and are vendor dependent. More importantly, some protocols simply do not have a method to script user actions on the client side.

For Login VSI, the choice was made to execute the scripts completely on the server side. This is the only practical and platform-independent solution for a benchmark like Login VSI.
