Symptom
When multiple target hosts in a Login VSI test are tested against, when the DDC connector is in use, there are performance difference from host-to-host. Also, it's already been verified the power settings are the same between target hosts.
Cause
The reason for this performance difference could be different target hosts have different amounts of target VMs on them at that point in time.
Resolution
Make sure either of the following is performed before testing to ensure best results:
- Target VMs are load-balanced manually across hosts
- Or the connection command-line from CSV feature is setup in the Login VSI Management Console, ensuring the VMs will be connected to in the desired order for testing
Note Login VSI will connect to targets with sequential usernames by default.
This is recommended best-practice because, when using the DDC connector, as it will bypass the load-balancing logic typically provided by the connection servers and brokerage resources. It will connect directly to the target desktops instead avoiding a connection protocol layer.
