🚀 We achieved 629 ns deterministic latency with eBPF/XDP + 5.1 GHz isolated cores In high-frequency trading, AI training clusters, and 5G URLLC environments, every nanosecond matters. Traditional Linux networking ( iptables / nftables ) adds ~5,000 ns latency with high jitter — creating expensive synchronization walls. So we built NanoPAM (Aegis-XDP) — a transparent Layer-2 stealth bridge that moves full Privileged Access Management + token-bucket rate limiting directly into the XDP fast path . Results on isolated 5.1 GHz cores: P50 (Median) : 629 ns P99 : 645 ns Jitter variance : < 41 ns ~8,000× faster than standard Netfilter Full technical deep-dive (with architecture diagrams, benchmark tables, jitter graphs, CPU isolation details, and code) is here: → [Read the full story on Medium] https://medium.com/@reachshankarg/how-we-achieved-629ns-deterministic-latency-using-ebpf-xdp-and-5-1ghz-isolated-cores-90a15f3e81e1 Would love feedback from the community — especially on the XDP implementation, CPU…
