Netty-CPU使用率高达100%

发表于 | 更新于: | 分类于 | | 热度: ℃

Netty做数据转发，但是CPU使用率太高了。

  • 解决方案：
    System.setProperty("org.jboss.netty.epollBugWorkaround", "true");//避免CPU使用率达到100%

Googling for sun.nio.ch.WindowsSelectorImpl$SubSelector high cpu brings up a few hits from as last at 2015. Are you running an older version of Netty?

Also see https://github.com/netty/netty/issues/3857 - you may want to try running with -Dorg.jboss.netty.epollBugWorkaround=true.
