About Login VSI, Inc.

Login VSI provides performance insights for virtualized desktop and server environments. Enterprise IT departments use Login VSI products in all phases of their virtual desktop deployment—from planning to deployment to change management—for more predictable performance, higher availability and a more consistent end user experience.

6 steps for the best VDI performance

Desktop virtualization promises flexibility, centralized management and data, and better security. But at the end of the day, VDI success comes down to one thing: End user experience. Whether you are using Citrix, VMware or Microsoft, the inherent complexity of your environment, compounded by constant application updates, can and will affect performance in your VDI environment. To help you to deliver a predictable performance, higher availability and a more consistent end user experience in every phase of your deployment, we would like to introduce the VDI lifecycle.

What our customers are saying

Maarten Bruijnesteijn

"We are using Login VSI for hardware scaling. By testing the number of users that can run on our environment, we know the amount of hardware that we will need upfront. We also use Login VSI in our production acceptance process to test changes to the system to evaluate changes to the environment."

Maarten Bruijnesteijn, System Software Analyst at PPG Industries

Chris Gebhardt

“We use Login VSI to make sure that what we are recommending to our customers is much better than what their guesses are. Because if you don't do proper assessment and if you don’t use Login VSI, your architecture is just a guess.”

Chris Gebhardt, Senior Technical Marketing Engineer at NetApp

Randy Groves

"As the developer of the PCoIP protocol, we do a lot of our own internal benchmarking to make sure that we’re continuing to improve our protocol. But we can’t actually publish our internal benchmarks because everybody might think that the tests are biased. So when we want to publish results, we use Login VSI. That way, if a customer wants to repeat our results they can.”
