Another potential source of these “Java heap space” OOMs arises with the use offinalizers. If a class has afinalizemethod, then objects of that type do not have their space reclaimed at garbage collection time. Instead, after garbage collection, the objects are queued for finalization, which...
Proper memory management in Unity can be challenging. The goal of this guide is to fit you with the necessary knowledge to profile and optimize memory consumption on any publicly available platform.

自然的基本规则,例如光速和一般信息理论,对我们从传统系统架构中获得的最大性能设置了重大限制。了解作为Java开发人员,您可以使用in-JVM技术和Java Streams以数量级提高性能。 例如,如果应用服务器和数据库服务器相距100米(约330英尺),则光速所引起的往返延迟略微超过600 ns。更重要的是,由于TCP / IP协议处理,10 ...
I've relatively new to Java and IntelliJ, and have developed an agent based model which takes a long time to run. I thought that running multiple instances in parallel would speed it up so I allowed multiple instances in the run configuration. I ran four...
Memory leaks come in various types such as thread and ThreadLocal leaks, ClassLoader leaks, system resource leaks, and connection leaks. Approaches to memory leak detection typically involve examination of Java virtual machine tool Interface (JVMTI) or p
When Confluence Data Center stops working and java.lang.OutOfMemoryError is appearing in the logs, adding memory to the JVM heap will get things running again. Solution Error type and memory size Java applications like Jira, Crowd, and Confluence run in a "Java virtual machine" (J...
