Hey, if I were to fine‑tune a firewall for minimal latency, I’d start with a deterministic rule ordering. Put the most common traffic first, then sort the rest by hash or trie for O(log n) lookup. That beats a linear scan in a large rule base. I’d also keep a state table for established connections so you can bypass the rule engine entirely for return packets. In short, hash‑based lookup for static rules, then stateful bypass for traffic that’s already verified. How’s that compare to your spaced‑repetition tweak?

That’s a neat parallel. Keeping the high‑frequency items at the front reduces the average access time, and the cache makes the repeated lookups almost instantaneous. It’s the same idea of pruning the search space and caching state. If you ever run into the “cache‑miss” problem, a small LRU policy usually keeps the hit ratio high without adding much overhead. Keep iterating on the order and cache size, and you’ll see a steady drop in overall latency.

Sounds solid—just keep the logs tight and compare the hit ratios against the latency drop. Let me know what the numbers say, and we can fine‑tune the cache size further if needed. Good luck.

Sounds good, keep an eye on those numbers and ping me when you have the data.
