VDI Load Testing: When do I need an extra VSIshare?

VDI Load Testing: When do I need an extra VSIshare?

Why do people perform load tests of their virtualized desktop environment? Most likely to get more insight in the performance and maximum capacity of their environment. In order for Login VSI to give you these test results we need data--lots of data. That’s why during a large-scale Login VSI test, logfiles are continuously sent to the VSIshare and sessions are also doing read actions on the files that are located in the VSIshare. This means that a lot of data is written to the VSIshare and sometimes your VSIshare can get overloaded. This can have a negative impact on your test because of 1. loss of test data and 2. timeouts during copy actions.

Scheduling automatic Login VSI performance tests for your virtualized desktop environment

Scheduling automatic Login VSI performance tests for your virtualized desktop environment

Wouldn’t it be great to exactly know the maximum capacity of your virtualized desktop environment on a week-to-week basis? Recently a customer asked us if it is possible to schedule a Login VSI load test to automatically start running during the weekends. One of the reasons for this was that the company wanted to have a performance overview of the environment every Monday morning. Although we do not recommend simulating thousands of virtual users in your live production environment, it is not only possible to schedule tests but doing so can save you time while you regularly gauge performance.

Login VSI supports Windows 10 for virtualized desktop performance testing

Login VSI supports Windows 10 for virtualized desktop performance testing

How will Windows 10 perform in your virtualized desktop environment?

On the first day of October last year, I got my hands on the technology preview of Microsoft Windows 10. Of course, I immediately checked if Login VSI would run on this brand new operating system. Within hours after the release I was able to verify that all tests ran smoothly.

Getting Started Video Series for Login VSI

Getting Started video series for Login VSI

I learned that Jurassic World brought $511.8 million in revenue in its first few days. This made me think about updating the Getting Started videos for Login VSI 4.x. With more than 10,000 views in one year, the previous Getting Started video was *almost* as successful as Jurassic World. I’m hoping better CGI, more explosions and even more realistic screen captures will skyrocket view numbers.

Disconnected Sessions - Login VSI Support Perspective

Disconnected Sessions - Login VSI Support Perspective

This blog post will talk about disconnected sessions. Disconnected sessions can be a real annoyance during a Login VSI test as they can be hard to diagnose and even harder to solve. I hope to give you a better understanding of what is causing disconnected sessions so that you can begin to avoid them and continue with a successful Login VSI test.

Importing Citrix XenServer Performance Data into Login VSI

Importing Citrix XenServer Performance Data into Login VSI

When doing tests using Login VSI, external data can be imported into the Login VSI Analyzer. By importing this external data, you get full insight on your environment’s performance. On VMware vSphere, for example, esxtop can be used to collect performance data about VMware vSphere hosts. This performance data contains data about host CPU usage, memory usage or disk I/O.

A hidden gem for Login VSI workload customization: Problem Steps Recorder in Windows

A hidden gem for Login VSI workload customization: Problem Steps Recorder in Windows

Every now and then you run into some very useful tools on the Internet, but sometimes you even manage to find a hidden gem somewhere within the operating system you have been using for so many years. Today I would like to introduce (or re-introduce) you to such a tool: Problem Steps Recorder. Problem Steps Recorder is helpful in all those situations where a user has to explain to you what they are actually doing. Instead of trying to repeat the process with these (typically) vague descriptions, Problem Steps Recorder will take screenshots and notes of every step in the process.
