Bridging the Gap Between Data Science & Engineer: Building High-Performance T. typed languages (Java, C or C++), performing most type-checking at runtime. The same principles apply to other DTOs in any other business area. Using Java Technology Reflection to Improve Design. 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. Even for the most internally efficient libraries, this inevitable serialization procedure will largely dictate performance.
Some of my measurements showed more than 1000 performance improvement.
#Java reflection performance improvement code#
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. By creating and reusing delegates, you can optimize your reflection code multiple times. Tuning is an iterative process: you normally find one bottleneck, make changes that improve performance, test those changes, and then start again. 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. Abstract: We give some advice on improving the execution of Java programs by reducing their time and space consumption. Read this article and become aware of different ways to improve Java serialization performance. This article elaborates on different ways of serializing Java objects and benchmarks performance for the variants.
