To provide the most optimal user experience, this approach leverages the capabilities of a UPM solution and requires additional image preparation and can incur some additional image management overhead. -The following describes many performance improvements in stateful non-persistent deployments. For more information, see Sequencing Steps to Optimize Packages for Publishing Performance later in this topic. |
-The general expectations of the previous scenario still apply here. However, keep in mind that VM images are typically stored in very costly arrays; a slight alteration has been made to the approach. Do not pre-configure user-targeted virtual application packages in the base image. -The impact of this alteration is detailed in the User Experience Walk-through section of this document. |

Configuration Setting | -What does this do? | -How should I use it? | -
---|---|---|
Shared Content Store (SCS) Mode -
|
-When running the shared content store only publishing data is maintained on hard disk; other virtual application assets are maintained in memory (RAM). -This helps to conserve local storage and minimize disk I/O per second (IOPS). |
-This is recommended when low-latency connections are available between the App-V Client endpoint and the SCS content server, SAN. |
-
PreserveUserIntegrationsOnLogin -
|
-If you have not pre-configured (Add-AppvClientPackage) a specific package and this setting is not configured, the App-V Client will de-integrate* the persisted user integrations, then re-integrate*. -For every package that meets the above conditions, effectively twice the work will be done during publishing/refresh. |
-If you don’t plan to pre-configure every available user package in the base image, use this setting. |
-
MaxConcurrentPublishingRefresh -
|
-This setting determines the number of users that can perform a publishing refresh/sync at the same time. The default setting is no limit. |
-Limiting the number of concurrent publishing refreshes prevents excessive CPU usage that could impact computer performance. This limit is recommended in an RDS environment, where multiple users can log in to the same computer at the same time and perform a publishing refresh sync. -If the concurrent publishing refresh threshold is reached, the time required to publish new applications and make them available to end users after they log in could take an indeterminate amount of time. |

¹ The publishing operation (Publish-AppVClientPackage) adds entries to the user catalog, maps entitlement to the user, identifies the local store, and finishes by completing any integration steps. |

|
-Because the add/refresh must re-configure all the virtual applications to the VM, the publishing refresh time on every login will be extended. |

---|---|---|---|
No Feature Block 1 (FB1, also known as Primary FB) |
-No FB1 means the application will launch immediately and stream fault (application requires file, DLL and must pull down over the network) during launch. If there are network limitations, FB1 will: -
|
-Stream faulting decreases the launch time. |
-Virtual application packages with FB1 configured will need to be re-sequenced. |
-
Step | -Considerations | -Benefits | -Tradeoffs | -
---|---|---|---|
No SXS Install at Publish (Pre-Install SxS assemblies) |
-Virtual Application packages do not need to be re-sequenced. SxS Assemblies can remain in the virtual application package. |
-The SxS Assembly dependencies will not install at publishing time. |
-SxS Assembly dependencies must be pre-installed. |
-
Step | -Considerations | -Benefits | -Tradeoffs | -
---|---|---|---|
Selectively Employ Dynamic Configuration files |
-The App-V client must parse and process these Dynamic Configuration files. -Be conscious of size and complexity (script execution, VREG inclusions/exclusions) of the file. -Numerous virtual application packages may already have User- or computer–specific dynamic configurations files. |
-Publishing times will improve if these files are used selectively or not at all. |
-Virtual application packages would need to be reconfigured individually or via the App-V server management console to remove associated Dynamic Configuration files. |
-
Step | -Considerations | -Benefits | -Tradeoffs | -
---|---|---|---|
Account for Synchronous Script Execution during Package Lifecycle. |
-If script collateral is embedded in the package, Add cmdlets may be significantly slower. -Running of scripts during virtual application launch (StartVirtualEnvironment, StartProcess) and/or Add+Publish will impact the perceived performance during one or more of these lifecycle operations. |
-Use of Asynchronous (Non-Blocking) Scripts will ensure that the lifecycle operations complete efficiently. |
-This step requires working knowledge of all virtual application packages with embedded script collateral, which have associated dynamic configurations files and which reference and run scripts synchronously. |
-
Remove Extraneous Virtual Fonts from Package. |
-The majority of applications investigated by the App-V product team contained a small number of fonts, typically fewer than 20. |
-Virtual Fonts impact publishing refresh performance. |
-Desired fonts will need to be enabled/installed natively. For instructions, see Install or uninstall fonts. |
