Measured figures backed by this report (free)
These figures are not behind the paywall — they are the performance claims this site makes publicly, so anyone should be able to check them for free. What is paid for is the report itself: full method, per-level raw data, charts, screenshots and signatures.
480B production topology, long-context cold-recovery load: +29% at concurrency 8 (lower bound), +40% at the optimal operating point (concurrency 16), +35–36% whole-machine TP4×2.
Provenance: Measured, R2/R3
About the hosted edition
The hosted PDF is the brand-unified edition: the product is named FX100 throughout, the layout was rebuilt, and charts plus a numerical-verification appendix were added. All nine load levels match the signed original cell for cell — no measured value was added, changed, or recomputed. The signed original uses the legacy product name and is not hosted publicly to avoid confusion with the FX naming; it is available on request. Its MD5 (A66F5491F075F502BB0B2E2EFB0C101C) is printed inside this edition, so you can confirm you received the same file and then re-verify every number with fx_report/verify_r3.py.
