Explanation
The best command to use to improve the latency issue is D. # echo net.core.rmem max = 12500000' >> /etc/sysctl.conf # echo net.core.wmem_max = 12500000' >> /etc/sysctl.conf # sysctl -p. This command will increase the size of the receive and send buffers for the network interface, which can improve the network performance and reduce packet loss. The sysctl command will apply the changes to the kernel parameters without rebooting the system. The other commands are either incorrect or not suitable for this task.
