Reducing cpu jitter for deterministic performance
summary
Explains how to reduce CPU jitter that causes run-to-run variation and missed packets in low-latency apps by using the cpu-partitioning tuned profile to simplify system tuning, and demonstrates using eBPF to locate sources of CPU latency with an example showing improved, repeatable low-latency performance.
