Resolves #1079 (data report; the issue itself was closed as answered - this keeps the numbers with the other community reports).

Summary

Community benchmark report: Tesla V100-PCIE-32GB (sm_70) + Tesla P100-PCIE-16GB (sm_60) as the expert-helper cache (--expert-cache-device1 auto --remote-expert-opt), Qwen3.8-Flash-Next IQ3_XXS, 262,144-token context, engine 0.1.40.2 built from source (CUDA 12.8, sm_70+sm_60). This is the first mixed Volta/Pascal report: the maintainer's reply on #1079 asked for a bench PR with the data.

What changed

Adds bench/results/2026-10-07-community-v100-p100-helper/:

• README.md - report in the format of docs/COMMUNITY_BENCHMARKS.md (hardware, software, model hashes, exact launch config, method, results table, correctness checks, limitations).
• results.json - per-run engine timing blocks for all measured runs.
• engine-timings.txt - the engine's own timing lines for the battery.
• needles.json - tools/needle_bench.py output: 6 of 6 found (32k x3 depths, 128k x3 depths).
• strata-iq3_xxs.json - the complete server config.
• model-sha256.txt - model, mmproj, MTP and expert-profile hashes.
• bench_report.py - the measurement script (runs unchanged against any Strata server).

Key numbers (warm, single-sequence, 256-token cap, greedy, reasoning off): prompt 1,436.9 tok/s median at 17,971 tokens; 1,446.4 at 44,011; 1,410.5 single run at 119,731. Decode ~73 tok/s median. Two configuration notes measured for this rig: --prefill auto:32768 (the default 8192 chunk cap costs 50-100% prompt speed on helper-cache rigs - each >=1024-token chunk streams every non-resident expert) and STRATA_PREFILL_CPU_SHARE=auto (-23% TTFT on sub-1024-token prompts, output-identical in a fixed-prompt check).

No engine changes in this PR - results only.

Extra Notes

The rig has no P2P between the cards (different CPU sockets); decode includes the helper round-trip. The 0.1.39-to-0.1.40 decode delta and the helper-cache A/B were reported earlier in #1079.

Thanks for the pull request.

We're resetting the tracker for 0.2.0-beta. There are more than 1,300 open issues and pull requests, too many for us to review properly, so we're closing everything that isn't being worked on right now. Closed here does not mean rejected.

To reopen it takes about two minutes:

1. Rebase on main if it no longer applies, and re-run your checks on 0.2.0-beta.
2. Start the title with its area: [Engine], [GUI], [TUI], [Benchmark], [Docs] or [Other].
3. Fill in the pull request template: the problem and result, and the validation (what you ran, on which revision, what you saw).
4. Comment /reopen. A check runs and either reopens the pull request or lists what is still missing.

The rules are in CONTRIBUTING.md.
