Application Isolation Impact on the Citrix Presentation Server
One impact that Application Isolation has on the Presentation Server is a possible increase in hard drive and registry space utilized. This amount is application and isolation environment specific.
By default, an application which is isolated will make a copy of any application files (for example an ini settings file) and registry keys that the application opens for modification. Each copy is then virtualized per user. To avoid unnecessarily copying user data files, special file location such as “My Documents” are not virtualized by default.
It is possible, to reduce the amount of hard disk space used by fine tuning the rule-sets in the isolation environment.
Another impact that Application Isolation has on the Presentation Server is a possible increase in execution overhead. This run-time impact will be dependant upon the application’s usage of the registry and file system.
User Density using Application Isolation Environments
Depending on the type of application, using Isolation Environments will have some impact on user density. It largely depends on each application and user usage patterns (how often user interacts with the application). This is due to the fact that there is a layer of virtualization that is happening between the application and the operating system. Citrix recommends that you test the Application Isolation Environment with your own applications to ensure the highest level of satisfaction for the end users.
