This White Paper is a technical review of the Beta version of LoadGen from DeNamiK (http://www.DeNamiK.com). This new platform is designed for load/stress testing Citrix Terminal Servers. It offers the advantage of being simpler to use...

This White Paper suggests the need for a campaign to shorten the basic HAL timer, used by the OS for a variety of purposes. The result is that as clocking speeds of our systems increase, the OS becomes less efficient. Our systems,...

This is the original White Paper that used the phrase "Perceived Performance", written back in 2003. This White Paper explains a concept we are often describing to customers - "Perceived Performance". In this paper, we describe a...

This White Paper examines the use of Processor Affinity, the assigning of processes and threads to processors in a multi CPU system. In this paper, we describe different forms of Affinity, show some examples that you can try which help...

This White Paper, presented at BriForum 2005 (http://briforum.com), presents updated research in the area of Perceived Performance. A new method of displaying results (the Perceived Performance Profile) is used as a tool to investigate...

For a while, TMurgent was doing some Software Development for a number of vendors selling into the IT space.  This paper was aimed at those Citrix/Microsoft partner companies we were working with. This White Paper is the first of the...

This White Paper, which provides ISVs with information on handling software crashes in the field, comes in two parts. In Part I, we visit "Dr Watson" (drwin32), a technique for recovering crash information from any windows platform....

This White Paper, provides ISVs with an overview on porting C++ applications to the x64 platform. This paper covers both Win32 GUI apps as well as Windows Services. The paper is based on the results of porting a number of applications,...

This is the first public white paper suggesting some best practices for Sequencing in SoftGrid (the old name of the App-V product).  It was probably written against SoftGrid 3.5 or so. It was associated with a two part video, Advanced...

This is a White Paper, which I wrote for Sage Software (http://www.sage.com), the parent company that makes ACT! It was part of a project to help certify how the product installs and performs under Citrix. As they didn't seem to copyright the...

This White Paper looks at x64-bit servers and software applications. It looks into the question of. whether we really want run-of-the-mill software applications to be 32-bit or 64-bit on the x64 platform. Some test results, plus an...

This is a White Paper, which I wrote for Sage Software (http://www.sage.com), the parent company that makes SalesLogix. It was part of a project to help certify how the product installs and performs under Citrix. In this case they did...

This White Paper is a look at the new System Center Operations Manager (SCOM) Management Pack supporting App-V 4.5 released by Microsoft. In this paper, which is more of a product review, we look at the installation and configurability of...

This White Paper takes a technical look into a product that proposes to automate and ease the pain of application migration by analyzing installation techniques and external library interfaces. This product, AppTiTude is from a company...

This short PDF explains HyperV_Mon, a free tool that you can download from the tools section of the website to better understand CPU performance in a Hyper-V world.

This PDF explains everything you might ever want to know about using the Microsoft App-V 4.5 Client in "Stand-Alone" Mode. It includes possible customization of the MSI and using the MSI with Streaming.

This White Paper explains changes to App-V Licensing that Microsoft made. It explains why so many people already have licenses for App-V!

This White Paper presents research on how App-V 4.6 "Dynamic Suite Composition", or DSC, works at a detailed level. In the tests described in this paper, we see that the implementation of DSC is not consistent, and leads to potential...

This is an update to Perceived Performance to look at VDI and thinking about Cloud Computing performance in the future. This was presented at Briforum 2011 in London and Chicago.

This paper outlines the authors current thinking around handling data, especially in the era of Cloud Computing. This was presented at Briforum 2012 in Chicago.

This White Paper presents research on how App-V 5 performs client side layering of file and registry systems. In particular, the paper shows how "Connection Groups" works at a detailed level, including Pellucidity of containers and the...
