Abstract: The time required to login to a remote or virtual desktop can be reduced by caching image data in a persistent memory location in-between remote desktop sessions. For instance, image data related to an image displayed on a client device during a first virtual desktop session may be cached after terminating the first virtual desktop session. The cached data can then be used to display the same image, or a correlated image, on the client device during a subsequent remote desktop session, thereby avoiding the need to re-transport the image data over a network. In a similar manner, cached image data can be shared between multiple users sharing a common local area network (LAN) in order to improve collective virtual desktop performance.
