-XX:-PrintGC 和 XX:-PrintGCDetails 标志有什么作用?
我在这里找到了 JVM 标志.有没有更详细的说明他们究竟做了什么?
I found the JVM flags here. Is there a more detailed explaination of what exactly they do?
推荐答案
设置此标志会将JVM进行的所有垃圾收集写入日志文件(或stdout，但用处不大)，并且可以分析这些通过这里提到的工具.使用这些信息，您可以微调您的垃圾收集配置.
Setting this flags writes all the garbage collections made by the JVM to a log file (or stdout, but then it is less useful), and these can be analysed by tools such as the ones mentioned here. Using this information you can fine tune your garbage collection configuration.
