1.关闭中断平衡守护进程
systemctl status irqbalance
systemctl stop irqbalance
systemctl disable irqbalance
2.脱离中断平衡守护进程
# 编辑/etc/sysconfig/irqbalance
# 将指定CPU核心从中断平衡守护进程的列表中脱离（下为8-15）
IRQBALANCE_BANNED_CPUS=00000000,0000ff00
3.查看设备中断
cat /proc/interrupts/
4.将CPU掩码写入中断smp_affinity文件
echo 0x0004 > /proc/irq/50/smp_affinity
