Optimizing Citrix?? XenDesktop?? for High Performance

By: Craig Thomas Ellrod

Overview of this book

Citrix XenDesktop is a suite of desktop virtualization tools designed to provide users with fast and convenient access to their Windows desktops and applications through any device. Virtual desktops mean that rather than setting up hundreds or thousands of individual computers in an enterprise, companies can instead opt to create servers with large amounts of memory, disk, and processing resources, and use virtualization to offer these resources to end users. The result of this is that users are provided with an experience that appears to be identical to having an individual desktop PC. Each user has some disk space, processor time, and memory allocated to them, as though it is present on their own physical machine, when in reality, the resources are physically present on a centralized server. This book starts by answering the basic questions you need to ask when considering XenDesktop, followed by methods of how you can properly size your server infrastructure for XenDesktop. You’ll discover how to optimize the virtual machines used in XenDesktop, how to optimize your network for XenDesktop, and how to optimize the hypervisor and the cloud. You’ll also learn how to monitor XenDesktop to maximize performance. By the end of the book, you will be able to plan, design, build, and deploy high performance XenDesktop Virtualization systems in enterprises. You will also know how to monitor and maintain your systems to ensure smooth operation.

Citrix Receiver™ tweaks


In most cases, you will not need to tweak the Citrix Receiver application on the end user device. In the rare instances that your end user happens to be on the other side of the globe using international connections, using satellite or on an oil-rig platform at sea, then you might want to consider these. In other words, if the network latency between the end user and the XenDesktop datacenter is greater than 200 ms, then you have a case for tweaks. Otherwise, leave the defaults.

Configuring Citrix Receiver will take some research. Some tweaks can be done with GPOs while others can be done with registry settings. Citrix doesn't put those into one nice easy place to get to or manage. You may have to search for them, but some of that is done for you at.

Caching

Bitmap caching stores commonly used images on the client's local disk. If you have a high speed LAN, you don't need to use the following parameter:
