Performance Engineering

Master Kubernetes HPA v2 with custom Prometheus metrics. Implement Prometheus Adapter, PromQL rules, and fine-tuned autoscaling to prevent latency spikes.

Compare DPDK vs XDP for high-speed Linux packet processing. Evaluate kernel bypass versus in-kernel eBPF datapaths, latency, and production tuning.

Disabling CPU mitigations yields 5% to 30% I/O gains but exposes memory to side-channel exploits. Here is the operational risk vs reward guide.
