Hey r/eBPF,

I recently open-sourced AI Agentic Nano Previlaged Access management (NanoPAM) (Aegis-XDP) — a transparent Layer-2 bridge that does port-level PAM + token-bucket rate limiting entirely in XDP.

We achieved:

• P50 = 629 ns

• P99 = 645 ns (<41 ns variance)

• 8,000× faster than traditional Netfilter/iptables

Full technical deep-dive (with architecture diagrams, benchmarks, and jitter graphs) is here:

Would love feedback from the eBPF community — especially on the XDP fast path and CPU isolation approach. Thanks!
