Tuning Linux Servers for UW/webNetwork Performance

Tuning Linux Servers for UW/webNetwork Performance

The following changes will make sure Linux will clear unused connections faster:

Important: This solution requires adjusting Linux kernel parameters. You should make a note of the original values so you can reset them if necessary.

  1. To reduce the timeout wait time for closed sockets, change the value of the kernel parameter from its default of 60 to a smaller number, for example, 30.
    sysctl -w net.ipv4.tcp_fin_timeout=30

  2. To increase the maximum number of ports available to applications. Change the value of the kernel parameter from its default of 28232 to a higher wider range, for example, 1024 to 65535.
    sysctl -w net.ipv4.ip_local_port_range=1024 65500
The values specified here are just examples, you may have to try different values based on your systems load.
