Tuning network performance adjusting kernel parameters

You can achieve a higher network throughput changing some default parameters that may prevent your system to deliver more packets per second or to buffer properly.

Before you apply this setting below, read additional sources [1].

The parameters that can be set in /etc/sysctl.conf are:

kernel.shmmax=268435456  # for 32-bit
kernel.shmmax=1073741824 # for 64-bit
kernel.msgmni=1024
fs.file-max=8192
kernel.sem=”250 32000 32 1024
