1. System Level performance tuning
1.1. CPU frequency
Where performance "score" is the key index for benchmarks/applications tests, make sure CPU frequency is set to "performance", which is usually set to "conservative" by default.
sudo cpupower frequency-set -g performance
to check the current settings and CPU frequency:
sudo cpupower frequency-info
sudo cpupower -c all frequency-info | grep "current CPU frequency"
1.2. limits
add below to /etc/security/limits.conf and reboot
* soft noproc 65535
* hard noproc 65535
* soft nofile 655350
* hard nofile 655350
* soft memlock 60397977
* hard memlock 60397977
1.3. disable firewall
sudo systemctl stop firewalld.service
sudo systemctl disable firewalld.service
1.4. disable selinux
