    摘要： Less data to transmit from a server to a virtual machine on a client is achieved by transmitting only those methods of classes that the executed application actually requires. This is accomplished by taking the classes of the targeted application and statically determining which methods of these classes, as well as of the library classes, can actually be used by the application. A method usage map of usable methods for each class is saved in a file. When the request to download is received from the client, the server consults this map and selectively transmits only those methods that are in it. This saves download time and memory space in the virtual machine and speeds up execution.

    摘要： A profiling program determines a set of routines that impacts the performance of a selected root routine. Because the set of routines impacts the performance of the routine of interest, the members of the set are excellent candidates for profiling in order to more precisely measure the performance the selected root routine. Thus, routines that cannot be reached from the root routine need not be profiled, thereby reducing the amount of profiling code injected into a target program, and thereby reducing execution inefficiency of the target program.

    摘要： A smaller footprint is loaded into the virtual machine by loading only those methods of library classes that the executed application actually requires. This is accomplished by taking the classes of the targeted application and statically determining which methods of these classes, as well as of the library classes, can actually be used by the application. A generated method usage map of usable methods for each class are saved in a file. At runtime, the virtual machine consults this file and selectively loads into memory only those classes listed in the file. This saves memory space in the virtual machine and speeds execution.
