Rather surprised to see the performance scaling of nftables is so bad compared to iptables, especially as many distros switched to nftables by default some time ago.
I do understand that synthetic benchmarks of firewalls are difficult, and that you are supposed to use the advanced features of nftables (e.g. sets, maps) to express the same filter in fewer rules.

comment from "comex", in a thread discussing a mistake in an LLM-generated commit:

"(Disclaimer: I am not sashal.)

…In other words, you're saying that the patch is buggy because it drops the __read_mostly attribute (which places the data in a different section).

That's a good reminder of how untrustworthy LLMs still are. Even for such a simple patch, the LLM was still able to make a subtle mistake.

To be fair, a human could definitely make the same mistake. And whatever humans revie…
Comment by "adobriyan" showing the commit in question, which replaces a "struct hlist_head event_hash[EVENT_HASHSIZE] __read_mostly" with "DEFINE_HASHTABLE(event_hash, EVENT_HASH_BITS)"
