第5章 Available GC The Java HotSpot VM includes three different types of collectors, each with different performance characteristics. Java虚拟机有三种不同类型的gc,他们有不同的特性. 顺序gc The serial collector uses a single thread to perform all garbage collection work, whi…

第三章 Generations One strength of the Java SE platform is that it shields the developer from the complexity of memory allocation and garbage collection. However, when garbage collection is the principal bottleneck, it is useful to understand some aspec…

第二章 Ergonomics Ergonomics is the process by which the Java Virtual Machine (JVM) and garbage collection tuning, such as behavior-based tuning, improve application performance. The JVM provides platform-dependent default selections for the garbage col…

微软已经将AOT的包移到Nuget了,之前是在实验测试服务器上的.并且由之前的alpha版本改成了preview版本. C#的开发效率,接近C++的运行效率,而且可以防止反编译,可以支持大部分反射功能.还有几个小问题,暂时不能支持x86,win7上运行aot的程序可能需要打补丁! CPF里使用AOT需要将项目改成net5以上版本,因为net5之后才有COM的包装器,如果你只是给自己的控制台程序AOT的话,可以用低版本的netcore 使用方式很简单,编辑csproj,加入下面一段代码,另外CPF…

第六章 并行GC The Parallel Collector The parallel collector (also referred to here as the throughput collector) is a generational collector similar to the serial collector; the primary difference is that multiple threads are used to speed up garbage colle…

第九章 G1 GC The Garbage-First (G1) garbage collector is a server-style garbage collector, targeted for multiprocessor machines with large memories. It attempts to meet garbage collection (GC) pause time goals with high probability while achieving high…

collector种类 GC在 HotSpot VM 5.0里有四种: incremental (sometimes called train) low pause collector已被废弃,不在介绍. 类别 serial collector parallel collector( throughput collector ) concurrent collector(concurrent low pause collector) 介绍 单线程收集器使用单线程去完成所有的gc工作,没有线程间的…

第七章 并发gc Java 8提供两种并发gc,CMS和G1 Concurrent Mark Sweep (CMS) Collector This collector is for applications that prefer shorter garbage collection pauses and can afford to share processor resources with the garbage collection. CMS GC适用于偏好尽可能短的gc时间(因为gc会造…
