摘要： There is provided a computer implemented method for determining the efficiency of a runtime compiler. A set of execution times representing the time taken for program code to perform a set task after two or more runtime compilations is recorded. A first metric as the difference between the first execution time and the last execution time of the set of execution times, a second metric as the average throughput improvement from the set of execution times, and a third metric as the time taken for the compiler to achieve the maximum throughput from the set of execution times is calculated. Finally, an efficiency metric is calculated using the first, second and third metrics to determine the efficiency of the compiler.

摘要： One aspect of the present invention involves storing the operating time offset of a thread within an area of memory of the thread, and storing a load time and a relative load time for each frame of the thread stored within an area of memory of the frame. The operating time offset tracks the amount of time the thread has actively operated, the frame load time tracks the actual time the frame was loaded, and the relative frame load time tracks the time the frame was loaded after being adjusted for the inactivity of the thread. When a thread dump is performed at a specified time, a frame age and a relative frame age can be calculated for each frame based on the time of the thread dump, the operating time offset of the thread, the load time of the frames within the thread, and the relative load time of the frames within the thread.
摘要翻译：本发明的一个方面涉及将线程的操作时间偏移量存储在线程的存储器的区域内，并且存储在存储在帧的存储器区域内的线程的每个帧的加载时间和相对加载时间。操作时间偏移跟踪线程主动操作的时间量，帧加载时间跟踪加载帧的实际时间，相对帧加载时间跟踪在针对线程不活动进行调整后加载帧的时间。当在指定时间执行线程转储时，可以基于线程转储的时间，线程的操作时间偏移量，帧内的帧的加载时间，为每个帧计算帧时间和相对帧时长线程以及线程内的帧的相对加载时间。

摘要： The use of heap memory is optimized by extending a cache implementation with a CacheInterface base class. An instance of a ReferenceToCache is attached to the CacheInterface base class. The cache implementation is registered to a garbage collector application. The registration is stored as a reference list in a memory. In response to an unsatisfied cache allocation request, a garbage collection cycle is triggered to check heap occupancy. In response to exceeding a threshold value, the reference list is traversed for caches to be cleaned based upon a defined space constraint value. The caches are cleaned in accordance with the defined space constraint value.

摘要： Class loader changes from at least one user-defined class loader to a bootstrap class loader are determined by a stack processing module during de-serialization of a serialized data object. A reference to each user-defined class loader is stored separately from a thread method frame stack in response to each determined change from the at least one user-defined class loader to the bootstrap class loader. For each user-defined class load operation of a user-defined class associated with the de-serialization of the serialized data object, a latest user-defined class loader (LUDCL) is identified using the stored reference and the user-defined class is loaded using the identified LUDCL.
