Citrix has released a whitepaper on how to optimize the Logon process for XenDesktop and XenApp. In this whitepaper guide Citrix will give you an understanding Optimizing the Logon Process for XenApp and XenDesktop
The logon process for users accessing virtual desktops as delivered through Citrix XenDesktop or virtual applications as delivered through Citrix XenApp involves a variety of communication checkpoints and component interaction. Depending on the user environment and access location there can be an array of Citrix, Microsoft and possibly third-party components involved in the logon process. In order to optimize user productivity and enhance the overall virtual application and desktop experience, Citrix Consulting developed this white paper specifically focused on the logon process, common cause for logon delays and optimizations for improving the amount of time required to execute the logon process.
For an administrator to assess the logon process within their respective environment, the administrator must ensure that they have a detailed understanding of the logon process. This paper outlines the logon process for XenApp and XenDesktop, with a particular focus on identifying those key areas that commonly slow down the logon process. Each step of the logon process and each piece of component communication is outline in detail. With a solid understanding of the logon process, the reader is then introduced to the common causes of logon delays. This section provides a high-level aggregate of the logon delays that Citrix Consultants have encountered on customer engagements.
The common causes of logon delays serve as a high-level checklist that provide administrators with a reference point for investigating logon delays within their environment, but there is typically a need for quantifiable metrics to help guide an administrator through the process of determining which environment modifications and troubleshooting tools can be used to validate the delays to prove that modifications to the environment improved the actual logon times. The Citrix Consulting Solution Center team drilled into some of the common causes of logon delays to provide tangible metrics that can be referenced in any XenApp and XenDesktop environments. This whitepaper details the results and methodology of the Citrix Consulting Solution Center.
