Linux Server Tuned Daemon for Dynamic Performance Optimization

Lucas and Luna dive into the tuned daemon, a Linux tool that dynamically adjusts kernel parameters, CPU governor, disk elevator, and network settings based on workload profiles. They walk through how to install tuned on Ubuntu 24.04, inspect active profiles with tuned-adm, and explain the difference between throughput-performance and latency-performance profiles. Lucas shares a real-world example where switching from the default balanced profile to virtual-host improved database query response by 18 percent on a PostgreSQL server. They also discuss creating custom profiles for mixed workloads and demonstrate how to pin profiles to specific cgroups for multi-tenant isolation. If you manage Linux servers and want hands-off performance tuning without editing sysctl manually, this episode gives you a concrete starting point.
