linux – 如何判断irqbalance是否正在执行任何 *** 作？

概述我已经研究了提到在SMP系统上安装irqbalance( http://www.irqbalance.org/)的linux服务器调优文档.我现在正在四核系统上看它,虽然“ps axf”可以告诉我它正在运行,但我没有看到任何类型的统计数据或信息是否/如何影响系统. 谁知道在哪里看？ 在源代码中,他们引用/ proc几次.也许你在那里找到答案. root @ [/usr/local / src / 我已经研究了提到在SMP系统上安装irqbalance( http://www.irqbalance.org/)的linux服务器调优文档.我现在正在四核系统上看它,虽然“ps axf”可以告诉我它正在运行,但我没有看到任何类型的统计数据或信息是否/如何影响系统.
