Fluctuation in VDI Test Results you can solve with Login VSI

Fluctuation in VDI Test Results with Login VSI

As a test engineer at Login VSI, I perform many tests each day. But to give some scientific value to these test results, I usually repeat these tests at least 10 times to make sure that there is not a lot of variance between tests with the exact same settings. Some of our customers seem to struggle with getting consistent results in their own environment and that’s why they frequently ask me “How is it possible to get a different result when repeating a Login VSI test with the same identical settings?” In this blog, I will explain the most common reasons why this is happening and I will share some best practices on how to solve this.

VDI Reference Architecture Monthly – November 2016

VDI Reference Architecture Monthly – November 2016

Here we are again with another post for the Reference Architecture Monthly. I’m finding that there is a lot of great information with respect to proofs of claim and sizing, which is incredibly useful if you are trying to architect your own solution. In most cases these documents will carry this information, but what is more interesting is that there is almost always a unique morsel of information, sometimes hidden in the context of some great testing and analyzation. So, I’m going to start focusing on what I consider “the cool bits”.

Dell Precision Appliance for Wyse - VMware Horizon 7.0 with NVIDIA M10 Test Results

by Dell Wyse Solution Engineering

Summary

Looks like DELL has released an update to their hyper-converged Precision Appliance for Wyse to now include NVIDIA’s M10 GPU. Graphics rich experiences are becoming all the buzz lately and if you ask me, that is where I would want my desktop VM to live because the benefits for the end-users are massive. Typically, GPUs are seen as the elixir to what has been commonly referred to as a “laggy” experience, which basically expresses the feeling we have when there is time between a user action and the desktop (like clicking on the Start Menu in Windows) or seeing videos get all choppy.

VDI Performance Testing: To VSImax or not to VSImax

VDI Performance Testing: To VSImax or not to VSImax

When you are performing a VDI performance test with Login VSI, the most important part of any test are the results. But the result is only valid when you have completed a successful test, because there are many factors that can influence the test result. So how to make sure that a test was run successfully? One of the misconceptions that I hear quite often is that fact that you will need to reach VSImax for a test to be considered successful. In this blog I will explain the best way to determine if a test was successful or not.

Essential VDI Performance Graphs in the Login VSI Analyzer

Essential VDI Performance Graphs in the Login VSI Analyzer

Every user of Login VSI knows the “famous” VSImax chart in the Login VSI Analyzer. This chart is used in almost every VDI white paper of the major software / hardware vendors in our industry and basically shows the maximum capacity of your virtualized desktop environment. Besides VSImax, I frequently notice that many of our customers are not very familiar with the other charts in the Login VSI Analyzer. In this blog I would like to share some charts and features of the Login VSI Analyzer that I frequently use after a performance test.

Simulating VDI Users - Introduction to Login VSI Workloads

Simulating VDI Users - Introduction to Login VSI Workloads

Most people describe Login VSI as a “load generator”, but I don't feel this actually does it justice. The main differentiator between Login VSI and other load testing solutions is the fact that Login VSI generates load on a virtualized desktop environment by using virtual users to simulate the same behavior as your real users, instead of just static load. There's much more to consider when simulating those pesky and unpredictable humans. This enables any IT department to test the real-life impact of changes on the maximum capacity of their VDI environment without having to use (and bother) their real users.

Testing Citrix Published Applications is easy with Login VSI

Testing Citrix Published Applications is easy with Login VSI!

Hey there Login VSI fans. We are excited to release a new feature in Login VSI 4.1.7 for testing Citrix Published Applications with XenApp. We’ve been able to support Citrix XenApp for some time with some help from our professional services team, but now our default workloads are supported as hosted applications without the need for a published desktop or virtual desktop infrastructure (VDI) as the target. Of course we still provide support for any of your business critical applications you’d like to add to the workloads, and this new release makes that even easier.

Stop Wasting Time: How Time Settings Affect VDI Performance Tests

Stop Wasting Time: How Time Settings Affect VDI Performance Tests

Time zones are settings that are configured once by system administrators and are never looked at again. Why would you even bother to take a look at it again when everything works? That’s a very good question, but based on our own experience with customers, we know that the time settings are not always configured correctly. Not only can this affect your entire virtualized desktop environment, especially security authentication suffers from it, but it can also ruin your Login VSI test results. To avoid wasting your time, we will discuss time settings in this blog.

Three Lesser Known Tips for Your VDI Performance Tests (Login VSI Tips & Tricks)

Three Lesser Known Tips for Your VDI Performance Tests (Login VSI Tips & Tricks)

Two weeks ago I received an email from a customer asking if the colors in Login VSI graphs could be changed after analyzing a test. The customer mentioned that the colors don’t have enough contrast which makes it difficult to clearly distinguish the lines in the graphs. After asking our development team to implement this valuable customer feedback, it was immediately apparent that this functionality was actually already available in the Analyzer! That’s a quick way to deliver new functionality to our customers.
