在CentOS系统上提升JMeter性能,可以从多个方面进行优化。以下是一些关键的优化步骤和技巧:
sudo yum update -y
/etc/sysctl.conf
文件,添加或修改以下参数以提高性能:net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.tcp_fin_timeout = 30
net.ipv4.tcp_keepalive_time = 1200
net.ipv4.ip_local_port_range = "1024 65535"
net.ipv4.tcp_max_syn_backlog = 8192
net.core.somaxconn = 1024
net.core.netdev_max_backlog = 2000
net.ipv4.tcp_max_orphans = 32768
net.ipv4.tcp_syncookies = 1
sudo sysctl -p
vm.swappiness
值:vm.swappiness = 10
/dev/sda1 / ext4 defaults,noatime,nodiratime 0 0
net.ipv4.tcp_window_size = 10240000
net.ipv4.tcp_max_syn_backlog = 1024
net.core.somaxconn = 1024
net.ipv4.tcp_max_tw_buckets = 5000
net.ipv4.tcp_fin_timeout = 30
sudo systemctl stop firewalld
sudo systemctl disable firewalld
