Efficient Rebuilding of Large Java Heaps from Event Traces
Verena Bitto, Philipp Lengauer, Hanspeter Mössenböck · 2015
Understanding and tracking down memory-related performance problems, such as long garbage collection times and memory leaks, is a tedious task in large and complex applications. Memory profilers can support developers in this task by recording detailed traces of the application's memory behavior which can then be analyzed offline. Unfortunately, these traces can become huge, and processing them is a real challenge. If the goal is to rebuild the heap from a trace in order to analyze it, most state-of-the-art tools perform badly, because they are either too slow or provide only a coarse-grained view of the monitored application.
