[帮助文档] 查看ARMSJava探针的性能压测报告

ARMS探针在应用运行态进行字节码增强，实现应用性能管理能力。与其他通过字节码增强技术实现的性能管理方案一样，ARMS探针会带来一定的应用性能开销，但ARMS团队已经采用多项技术对探针进行优化，将探针的性能开销降低到极低的范围，以确保应用的稳定运行。在本篇测试报告中，我们模拟了真实的使用场景，测试A...

【小家java】HashMap原理、TreeMap、ConcurrentHashMap的原理、性能、安全方面大解析-----看这一篇就够了(中)

HashMap的扩容机制 resize()我们分析下resize的源码，鉴于JDK1.8融入了红黑树，较复杂，为了便于理解我们仍然使用JDK1.7的代码，好理解一些，本质上区别不大，具体区别后文再说。JDK8以后引入了红黑树对查询新能进行了优化。当Hash桶里面的数量大于8或者总容量大于64，就会转...
