红帽全球峰会4.2. 配置 Garbage Collector
虽然并行垃圾收集器（也称为吞吐量垃圾收集器）是 Java 8 中服务器级机器中的默认垃圾收集器，但红帽建议使用 G1 垃圾收集器，这应当是 Java 9 之后的默认垃圾收集器。在大多数情况下，G1 垃圾收集器的性能通常要优于 CMS 和并行垃圾收集器。
流程
要启用 G1 收集器，请使用以下 JVM 选项：
-XX:+UseG1GC
-XX:+UseG1GCCopy to Clipboard Copied! Toggle word wrap Toggle overflow
垃圾收集器日志选项
垃圾回收日志记录默认为独立的 JBoss EAP 服务器启用。要为 JBoss EAP 受管域启用垃圾回收日志，请参阅启用垃圾回收。
