All of them land in the same group_in, and _FindLinkIn() walks that group's grp->full list linearly for every packet. This hit a production hosting datacenter where I work as a consultant: one network thread was pinned at 100% with only a few hundred packets per second. We could not find the cause at the time. First we moved from ipfw to pf, and later the service was moved off FreeBSD to Debian/Proxmox. The datacenter lost a customer because of it. I found the root cause only later (two and half years later, with the application's source code and a lab that reproduces it. The behaviour is old: the same grouping existed in the pre-2021 hash table, as far back as libalias 1.0/2.1. Anyone running ipfw nat with redirects in front of a busy service can hit it. Change grp->full becomes an RB tree keyed by (dst_addr, dst_port), with a per-instance sequence number as a newest-first tie-break. That keeps the current semantics when several links share the same remote endpoint (3_natin:2_portoverlap depends on it). Partially specified links keep the existing list. The new field in struct libalias is appended at the end, because ipfw_nat.ko and ng_nat.ko read logDesc/packetAliasMode directly through alias_local.h. Results (16.0-CURRENT, VNET jails over epair, SYNs to one redirected port, 1000 pps): stock (~170k links) patched (~141k links) LibAliasIn per packet 1 to 2 ms 2 to 4 us packets per 10 s ~7,200 (saturated) ~10,000 (all offered) epair_task CPU 99% 0.0 to 0.15% Userland, 100k links in one group: a new SYN goes from about 1.25 ms to about 600 ns it was really fast. I also have a backport to 14.0 tested in userland. adrian@ accepted it and asked for more networking people to look at it. I am happy to run more tests, for example ng_nat or UDP endpoint independent mapping, if anyone has a scenario in mind. Thanks, Paulo Fragoso
