Linux Kernel Tuning for High-Throughput

Summary

Sysctl and kernel parameter optimization for high-throughput network services and database workloads.

Commands

sysctl -w net.core.somaxconn=65535

sysctl -w net.ipv4.tcp_max_syn_backlog=65535

sysctl -w vm.swappiness=10

sysctl -w fs.file-max=2097152

echo 'net.core.default_qdisc=fq' >> /etc/sysctl.conf

Conclusion

Kernel tuning provides measurable improvements for network-intensive workloads. Always benchmark before and after changes. Document all modifications — kernel updates can reset sysctl values.
