This is an optimization over standard Java Serialization which doesnt use reflection. In this article, we will use a Data Transfer Object (hereafter DTO) named MarketData which contains financial information with a relatively large number of fields. When deployed with Zing, Hazelcast gains performance, capacity. Even for the most internally efficient libraries, this inevitable serialization procedure will largely dictate performance. Physical Layer Data Link Application Monitor Reflection Notify Query/Reply Query Java. After all, this is only to be expected as Chronicle Queue (and other persisted queue libraries) must convert Java objects located on the heap to binary data which is subsequently stored in files. making that change results in an improvement in link performance. Some of my measurements showed more than 1000 performance improvement.
#Java reflection performance improvement code
In a previous article about open-source Chronicle Queue, there was some benchmarking and method profiling indicating that the speed of serialization had a significant impact on execution performance. By creating and reusing delegates, you can optimize your reflection code multiple times.
Read this article and become aware of different ways to improve Java serialization performance. If the identity of the class can't be determined, then the allocation code can't be inlined. Achieving an eightfold increase in performance by introducing a just-in-time compiler was a straightforward matter of engineering, and even though the compiler. Achieving equivalent performance with reflection-based instantiation requires you to write your code so the jit can tell which class is being instantiated. This article elaborates on different ways of serializing Java objects and benchmarks performance for the variants. Reflection is slow, though object allocation is not as hopeless as other aspects of reflection.
