Linux操作系统使用 tuned/tuned-adm工具动态调优CPU性能模式

Linux服务器CPU性能模式

环境:

  • Red Hat Enterprise Linux 4
  • Red Hat Enterprise Linux 5
  • Red Hat Enterprise Linux 6
  • Red Hat Enterprise Linux 7

On RHEL4:

configure the cpu speed to run at MAX speed all the time by adding the following parameter into the file /etc/cpuspeed.conf and restart the cpuspeed service:

vim /etc/cpuspeed.conf
插入或修改:
OPTS="$OPTS -n -C -S \\"0 1\\""
/etc/init.d/cpuspeed restart

On RHEL 5:

add the above parameters to /etc/sysconfig/cpuspeed or use the performance governor by adding the following parameter to the /etc/sysconfig/cpuspeed file and restart the cpuspeed service:

vim /etc/sysconfig/cpuspeed
插入或修改:
GOVERNOR=performance
/etc/init.d/cpuspeed restart

On RHEL 6:

configure the performance cpuspeed governor as above for RHEL 5 and add the following kernel boot options and restart the server. More information available in the Low Latency Performance Tuning for Red Hat Enterprise Linux 6 article.

/etc/init.d/cpuspeed stop		# 开启性能模式
processor.max_cstate=1 intel_idle.max_cstate=0 idle=poll

On RHEL 7:
