The Virtual Session Indexer uses a launcher workstation to start making sessions to your VDI or SBC clients/servers. In this session a script is run that will simulate a user session. The script will do things like; start some programs, browse the internet, write a document, etc. The launcher will keep starting new sessions until the performance of the client or server reaches a certain performance treshhold. It then stops launching sessions and spits out a report with all performance information from which the maximum user count is the most important.
You can now repeat this for every scenario you want to benchmark, think about the following scenario's;
- Terminal Server only vs Terminal Server with Citrix XenApp;
- Terminal Server or VDI running on VMWare ESX / Hyper-V / Citrix XenServer;
- Windows Server 32-bit vs 64-bit;
- Virtual Windows XP vs Virtual Windows Vista vs Virtual Windows 7;
- Different VDI technologies;
- Impact of Performance Optimization software like Appsense Performance Manager;
- Impact of different Virusscanners.
- The workload is now tuned and can be categorized to be medium/heavy load of a typical knowledge worker (this is in comparison to average Terminal Server deployments);
- The CPU workload may be categorized as medium/heavy (above average);
- The Memory workload is now medium (slightly above average);
- Many typical beta bug fixes, Login VSI is now battle proven in the benchmarking project: “Virtual Reality Check” by PQR and Login Consultants;
- Improved schema to calculate the optimal performance index.
