Embodiments provide an optimized virtual application or suite of virtual applications, but are not so limited. In an embodiment, components of a system are configured to generate an optimized virtual package that can be used in a virtual application streaming environment. Components of the system can provide bits of the optimized virtual package based in part on scenario mappings associated with a user action and/or an application or application feature. In one embodiment, a client virtualization handler can operate to download byte ranges of an optimized virtual package including re-prioritizing byte range download operations as part of streaming virtual application functionality over a computing network.
