A method, system, and computer-readable medium with executable code for enhancing real-time performance of a client device connected to a java virtual machine by incorporating a java proxy server. Java routing logic of a java proxy server is used to receive a request from a client device to access a java virtual machine. The java proxy server may use the java routing logic to select a java virtual machine from among multiple accessible java virtual machines. The java proxy server selects the java virtual machine that has the greatest amount of free memory, and is not performing a garbage collection operation. Once a java virtual machine is chosen, incoming client device connections are routed to a chosen java virtual machine. Additionally, the java routing logic may instruct one or more of the multiple java virtual machines to only perform garbage collection operations when idle, and when no other java virtual machines are performing garbage collection operations.

A method and a system for allowing a guest operating system (guest OS) to modify an entry in a TLB directly without an involvement of a hypervisor are disclosed. Upon receiving a guest TLB miss exception, a guest OS issues a TLBWE (TLB Write Entry) instruction to logic. The logic runs the TLBWE instruction at a supervisor mode without invoking a hypervisor. The TLB may incorporate entries in a guest page table and entries in a host page table.

Recording television programs for future playback by enabling the user to record a plurality of programs that have sequential units of commercial content. There is sequential sensing for commercial content units. When a commercial content unit is reached, it is removed for separate storage. A determination is made as to whether the removed commercial content unit is the same as a previous commercial content unit that has been removed. Any previous commercial unit that has been removed has been stored in a file and a pointer to the file inserted in place of the commercial in the sequential stream of the television program being recorded. Thus, if the removed commercial unit has the same content, i.e. is a repeat of a previous commercial, the inserted pointer will point to the file of the previous commercial.

Systems, methods and media for migration of a guest from one server to another are disclosed. In one embodiment, a first server, while hosting the guest, receives a signal from the second server that the migration is to occur. The first server presents the memory used by the guest as a virtual disk. The second server accesses this disk and copies its contents to the second server over the storage area network. The first server suspends operation of the guest, and after the memory of the guest is copied to the second server, the second server resumes operation of the guest.
