我不认为＆＃34; java.net.SocketInputStream.socketRead0＆＃34;有助于高CPU。通常＆＃34; java.net.SocketInputStream.socketRead0＆＃34;表示服务器正在等待从另一端收听，另一端响应缓慢。如果你没有看到＆＃34; java.net.SocketInputStream.socketRead0＆＃34;在您的其他环境中，您应该检查此特定环境的另一端（缓慢）。
有两种可能性：1。可能存在导致问题的其他线程（使用＆＃34;顶部＆＃34;使用＆＃34; H＆＃34;选项以找出消耗大部分线程的线程你的CPU）。 2. GC可能导致高CPU。
