我在JDK上启用了详细的GC选项,现在我看到了像这样的行:
25.598: [CMS-concurrent-sweep-start]
25.622: [CMS-concurrent-sweep: 0.023/0.024 secs] [Times: user=0.02 sys=0.00, real=0.03 secs]
25.623: [CMS-concurrent-reset-start]
25.629: [CMS-concurrent-reset: 0.007/0.007 secs] [Times: user=0.01 sys=0.00, real=0.00 secs]
有人能告诉我那些参数的含义吗?
- sys+user和real times的区别是什么?
- "0.023/0.024秒"代表什么意思?
