# 案例2：硬件优化
# 1. CPU优化
# 禁用CPU节能模式
cpupower frequency-set –governor performance

# 查看CPU频率
cpupower frequency-info

# 输出示例：
# analyzing CPU 0:
# driver: intel_pstate
# CPUs which run at the same hardware frequency: 0
# CPUs which need to have their frequency coordinated by software: 0
# maximum transition latency: Cannot determine or is not supported.
# hardware limits: 800 MHz – 3.60 GHz
# available cpufreq governors: performance powersave
# current policy: frequency should be within 800 MHz and 3.60 GHz.
# The governor “performance” may decide which speed to use
# within this range.
# current CPU frequency: 3.60 GHz (asserted by call to hardware)
# boost state support:更多学习教程公众号风哥教程itpux_com
# Supported: yes
# Active: yes

# 2. 内存优化

# AnonHugePages: 0 kB
# ShmemHugePages: 0 kB
# FileHugePages: 0 kB
# HugePages_Total: 1024
# HugePages_Free: 1024
# HugePages_Rsvd: 0
# HugePages_Surp: 0
# Hugepagesize: 2048 kB

# 3. 存储优化
# 配置磁盘调度器
echo “deadline” > /sys/block/sda/queue/scheduler

# 查看磁盘调度器
cat /sys/block/sda/queue/scheduler

# 输出示例：
# [deadline] cfq nonefrom DB视频:www.itpux.com

# 4. 网络优化
# 配置网络参数
echo “net.core.somaxconn=65535” >> /etc/sysctl.conf
echo “net.ipv4.tcp_max_syn_backlog=65535” >> /etc/sysctl.conf
echo “net.ipv4.tcp_fin_timeout=30” >> /etc/sysctl.conf
sysctl -p

# 查看网络参数
sysctl net.core.somaxconn
sysctl net.ipv4.tcp_max_syn_backlog
sysctl net.ipv4.tcp_fin_timeout

# 输出示例：
# net.core.somaxconn = 65535
# net.ipv4.tcp_max_syn_backlog = 65535
# net.ipv4.tcp_fin_timeout = 30
