The production image is built against musl, whose allocator is slow and takes a global lock. Profiling /json on a 1 CPU / 1 GB Alpine container showed malloc/free at ~11% of total CPU, the largest user-space cost; the rest is mostly the kernel network stack, already at one recvfrom and one writev per request. mimalloc alone, however, kept the freed ~96 MB MMDB buffer resident after a database update (RSS stayed at ~197 MB in two of three swaps), and MIMALLOC_PURGE_DELAY=0 fixes that only by giving back most of the speedup. So blocks of 1 MiB or more, in practice only the MMDB file contents, go to the system allocator, which unmaps them on free; RSS returns to ~98 MB after every swap, as before. Median of three alternating 20 s runs: /json across random IPs rose from 131.6k to 142.4k rps (+8%), p50 latency 0.465ms -> 0.443ms; a single IP rose from 124.5k to 127.4k rps (+2%). Steady-state RSS grows by ~12 MB. Responses are byte-identical to before. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
