Need to speed up streaming app launch time in Citrix

We are trying to stream office 2010 in Citrix and although it does work there is some lag when you launch the first app, maybe 20-30 seconds. Each app launch after the initial takes a fraction of that time. Is there a way to use raderun to "pre-cache" these items (i dont know if that is the proper term) so they dont have to copy down from the file server each time?

Pre-Delivering Streamed Applications. Administrators should consider pre-delivering large applications (100 MB+) to end-users with the ‘radedeploy’ command-line utility provided by Citrix. Pre-delivering applications that will be streamed to client workstations (rather than Citrix Presentation Servers) is especially useful if the endusers are located in remote branch offices or across fragile WAN links. Before pre-delivering all applications with the radedeploy utility, it is important for architects to consider the applications which are to be streamed to endusers.
For example, an application that requires frequent updates may not be the best candidate for pre-delivery.  For applications with a high update frequency, it may be best to pre-deliver the original profile and then use the built-in Application Streaming technology to handle the updates, since the application cache will be leveraged and only the small changes to the profile will be sent to the Streaming Client. If radedeploy is used, it is considered a best practice to pre-deliver all applications to client workstations during off-peak hours or hours with the lowest network utilization. Pre-delivering applications to Presentation Servers is also recommended – however, in most cases, the file servers or storage device where the profiles are stored are usually located logically near the Presentation Servers, where bandwidth is typically not as big as a factor as in the branch office delivery scenario.
