Linux system optimization

1. Optimize the maximum listening queue for the port
/proc/sys/net/core/somaxconn
Defines the length of the maximum listening queue for each port in the system, which is a global parameter with a default value of 128
The default of 128 is too small for a high-load Web service environment that often handles new connections. Most environments this value is recommended to increase to 1024 or more

We can modify this parameter by using echo >/proc/sys/net/core/somaxconn.
