Windows 10 Default File Type Associations and Login VSI

Login VSI Blog Article - Microsoft Windows 10 Default FTA Associations - Teaser Image

Back in 2013 when Login VSI 4.1 got released and the majority of desktops were running Windows 7 life was easy. We’d set the default filetype for an application and it would simply work.

The default and industry standard workloads in Login VSI include launching and using Adobe Reader as part of the virtual user simulation. Because Login VSI doesn’t always know which version of Adobe Reader is installed, or where it’s installed, the workload relies on the file type association (FTA) for .pdf documents to be associated with Adobe Reader.

The impact of Meltdown and Spectre patches on Windows 10

Testing with Login VSI to Solve the Problems Caused by Meltdown & Spectre

Over the last weeks a lot has already been written about the supposedly high impact that the patches of both Meltdown and Spectre will have on the performance of computer systems but even experts do not yet agree how big the impact will be on centralized desktop environments such as Microsoft RDS, Citrix XenApp & XenDesktop and of course VMware Horizon causing a lot of fear, uncertainty and doubt.

Simple tricks to improve Windows 10 performance by 3000%

Windows 10 - now 3000% better!

On October 2nd Microsoft released version 1809 (Codename: Redstone 5) for those who wanted to update manually.

On the 9th of October it started rolling out via automatic windows updates. Unfortunately there was an oversight in the update mechanism leading Microsoft to pause the update temporarily as during the upgrade users documents got deleted. While waiting for the fixed version of Windows 10 to be released we started doing our regular performance tests, as we did with Server 2019 and Office 2019 recently and the results where…well, not what we expected.

Citrix Virtual App user density on AWS

Login VSI workload testing on AWS EC2 instances

If you are in the End User Compute (EUC) space like me, you are undoubtedly aware of the annual VDI Like A Pro survey. In this survey we continue to see the trend of interest in the public cloud growing, however most of the respondents cited cost and performance as major concerns when considering cloud options. At Login VSI we are seeing more traction with enterprises adopting cloud strategies for their digital workspaces, and I am personally very excited about this.

Testing L1TF patches: Virtual Desktops on VMware ESX

Intel: what is L1 terminal fault?

Last week Intel announced 3 new severe vulnerabilities in their processors allowing unauthorized access to the data in the L1-cache. They have been named L1 Terminal Fault or in short L1TF. By now I assume most IT-admins are aware of this, but the performance impact remains a mystery. That’s why we took it upon us to get you this information as soon as possible. Please note that these are initial findings. As we are doing more research and get more results we will constantly publish new updates.

Testing Meltdown and Spectre patches: Citrix XenServer 7.2 versus 7.5

Meltdown and Spectre

A few weeks ago we published a blogpost around Meltdown and Spectre on XenServer 7.2. In the previous blogpost I mentioned that the results were surprisingly good and other then expected. This feeling kept bothering me and urged me to verify if the behavior and results were correct. After some research I found out that the patches were applied and that both used tools (Powershell and Inspectre.exe) to check this verified this.  I decided to install newer versions of XenServer to see if the results and behavior was consistent to what we saw with XenServer 7.2. I chose to focus on XenServer 7.5 as this is the latest version that XenServer currently supplies. I also updated it to the latest patch version (XS75E002).

To cope with all (IT related) changes that may impact application availability and therefore disturb business operations, most large organizations have implemented comprehensive and structured change management programs. Programs including pre- and post-testing planned changes with realistic user numbers, and pro-active detection of slowdown caused by unplanned changes or gradual deterioration.

Testing Meltdown and Spectre patches: RDSH (SBC and XenServer 7.2) using Windows server 2012R2 and Server 2016

Meltdown and Spectre

After all the news around Meltdown and Spectre it seems things are calming down now. Recent talks are focusing more on next-generation exploits rather than the performance impact. The Login VSI Meltdown and Spectre emergency edition has been a great success and helped many of our customers, vendors and community friends. I’d like to share some results from our internal performance validation labs where I’ve conducted tests on a large number of operating systems measuring the impact of patches on the OS, Hypervisor and BIOS level. Please keep in mind that this is a lab environment, results will vary on your own systems.
