Linux Architecture

Master Linux network namespaces and virtual Ethernet (veth) pairs. Trace kernel packet paths, eliminate latency bottlenecks, and debug container networking.

Master Linux memory reclamation tuning. Optimize vm.swappiness, vfs_cache_pressure, and watermarks to eliminate latency spikes and OOM stalls.

Isolate multi-tenant web workloads with systemd and cgroups v2. Prevent noisy neighbors while enforcing deterministic CPU, memory, and NVMe limits.
