docs(bench): add physical-machine baseline (13.0 vs 15.0) from iWiki 4021545579
Distill the external OSPF/CMC team's bare-metal A/B benchmark report
(Intel Xeon 8255C @ 2.5GHz + Mellanox CX-5 100G + TencentOS 4.4 +
Linux 6.6.98) into the FreeBSD 13.0->15.0 upgrade spec set, and
cross-link it with the in-project CVM same-timeline A/B baseline.
Headlines (physical machine):
* helloworld single-core long-conn: 958,109 -> 1,056,178 req/s (+10.24%)
p99 204us -> 197us (-3.43%); p50/p75/p90 all improved.
* nginx_fstack long-conn 1/2/4 cores: +5.06% / +4.76% / +4.83% net gain.
* nginx_fstack short-conn 1/2/4 cores: -2.25% / -3.65% / -6.10%;
4-core case crosses NFR-1 5% threshold by 1.10pp -> tracked as the
only systemic regression signal, with disposition options recorded.
Cross-platform reading vs the in-project CVM same-timeline A/B (helloworld
single-core: 13.0=220k -> 15.0=204k req/s, -7.59%): the +10.24% (bare metal)
vs -7%~-9% (CVM) delta-direction reversal upgrades the perf-flamegraph
root-cause conclusion in 13.0-baseline-cvm-bench-report.md S11.5 from a
single-evidence finding to a perf+cross-platform double-evidence finding.
The CVM 9% gap is vendor evolution (TCP stacks vtable / CUBIC / sb_locking)
amplified by the virtio_user path, NOT introduced by the runtime-fix series.
Files:
* NEW physical-machine-bench-report.md (251 lines, 9 sections):
platform, helloworld/nginx tables, CVM cross-comparison,
4 key findings, NFR-1 acceptance matrix, data-asset pointers.
* EDIT 06-test-and-acceptance-spec.md: add S5.4 Physical-machine
baseline (3 NFR-1 tables + 4 verdicts) and 2 link rows in S10.
* EDIT 13.0-baseline-cvm-bench-report.md: append S15 Physical-machine
baseline cross-reference (7 subsections); reaffirm S6.1/S6.3
narrative; explicitly tie each S11.5 root cause to its bare-metal
counter-evidence.
