一、系统配置-物理机-可能会有差异

#手工的执行如下的动作,使之立刻生效:

echo never > /sys/kernel/mm/transparent_hugepage/enabled

echo never > /sys/kernel/mm/transparent_hugepage/defrag

echo deadline > /sys/block/sda/queue/scheduler

echo "" > /sys/block/sda/queue/read_ahead_kb

echo "" > /sys/block/sda/queue/nr_requests

#减少预读：/sys/block/sda/queue/read_ahead_kb，默认128，调整为16

#增大队列：/sys/block/sda/queue/nr_requests，默认128，调整为512

echo "" > /sys/block/sda/queue/read_ahead_kb

echo "" > /sys/block/sda/queue/nr_requests

#如果是使用普通SAS盘的话,使用elevator=deadline

#如果是使用SSD/FLASH卡的话,使用elevator=noop

echo noop > /sys/block/sda/queue/scheduler

echo deadline > /sys/block/sda/queue/scheduler

#对于关闭透明大页的问题,也执行如下的操作:编辑 /etc/rc.local,添加如下内容
