Acceleration Software for Business-Critical Applications

Terminal Server Performance Tuning
Brian Madden's real-world, step-by-step approach to getting the most out of your Citrix XenApp or Microsoft Terminal Server systems.

Whether you’re experiencing slow logons, random pauses, or you’d just like accommodate more users on your server, this paper is your real-world field guide to techniques that will identify, troubleshoot, and resolve performance issues of Terminal Servers in your environment. It assumes that you've made the decision to use Terminal Services and that you would like to increase the performance of live servers that are currently up and running.

Conquering Rogue Application Behavior in a Terminal Server Environment
In Terminal Server environments, every application that each user is running must share the CPU resources of the server on which they are running. Sometimes applications “go rogue” by consuming too many CPU resources. When this happens, all of the users experience sluggish response times and IT administrators must spend time troubleshooting and correcting the issue.

RTO Software’s TScale® solution offers Application Shaping™ which automates processor affinity assignments, application priority changes, and CPU load balancing to provide IT administrators with pinpoint application control. With Application Shaping, TScale gives you the tools to overcome problems associated with rogue applications and provide consistent and reliable application performance and responsiveness even during peaks in application demands.

Addressing Terminal Server Scalability and Performance
In most cases, CPU utilization is not the major factor limiting your terminal server capacity. The fact is that the virtual memory nature of these operating systems and single-user applications forced to run in a multi-user environment imposes significant demands on a server. This white paper explores issues associated with the performance and scalability of terminal servers, and the applications that run on them.

Five Ways to Maximize Value of Future IT Investments
This thought leadership white paper discusses several key issues that will impact your company as it moves toward a Service-Oriented Architecture (SOA) and Web Services technologies. The paper drills down on five critical strategies that can help you transform your existing infrastructure to a next-generation model, including the need to:

• Recognize that it's not enough to have the fastest, most robust hardware
• Make a distinction between revenue-generating and administrative-support applications
• Set a plan for critical path monitoring
• Align system and application performance metrics with business metrics
• Establish a plan to guard against security threats and generate audit trails to meet regulatory requirements

Learn more about moving to a next-generation infrastructure and how you can gain the maximum value and business success from those investments.

RTO Terminal Services Scalability Study
Part 1: The Effect of Citrix Presentation Server 4.0

Performance and scalability are essential for your terminal services farms. However, an understanding of the true scalability of Terminal Services or Citrix environments represents the Holy Grail for terminal server architects planning roll‐outs in such environments. Unfortunately, most testing environments fail to comprehend many of the effects of the complex interactions in each of these environments, and do not accurately reflect the true scalability.

Therefore, we set out to conduct a series of experiments in three parts. This paper constitutes PART 1 of the series and is focused primarily on determining the overhead for terminal services clients running desktops. It compares Remote Desktop (RDP) clients and Citrix Presentation Server (ICA) clients while also taking into account the overhead for resources used by Citrix Presentation Server 4.0 (MPS4.0) once it is installed on a server.

RTO TScale Product Evaluation Report
This product evaluation report that we completed for Corporate Synergies demonstrates how RTO TScale increases application virtual memory utilization and scalability of an application server. The actual virtual memory savings for several business productivity applications are listed. When you multiply these results per user, the virtual memory savings add up and increase server scalability.
