使用完全公平调度程序（CFS）进行多任务处理: http://www.ibm.com/developerworks/cn/linux/l-cfs/
[root@dodge ~]# sysctl -A|grep "sched" | grep -v "domain"
kernel.sched_min_granularity_ns = 4000000
kernel.sched_latency_ns = 40000000
kernel.sched_wakeup_granularity_ns = 2000000
kernel.sched_batch_wakeup_granularity_ns = 25000000
kernel.sched_stat_granularity_ns = 0
kernel.sched_runtime_limit_ns = 40000000
kernel.sched_child_runs_first = 1
kernel.sched_features = 29
kernel.sched_compat_yield = 0

CFS scheduler tuning
CFS (Competely Fair Scheduler) is the name of the Linux process scheduler. By default it is tuned for desktop workloads. For server systems where throughput is more important than latency, Red Hat’s tuned package proposes these sysctl settings for CFS for servers:
kernel.sched_min_granularity_ns = 10000000
kernel.sched_wakeup_granularity_ns = 15000000
