feat(bench): add minibf performance regression harness - #1318
Conversation
📝 WalkthroughWalkthroughThe change adds measured archive fixtures, backend query benchmarks, and a Minibf benchmark system. It supports synthetic and real-data workloads, HTTP calibration, live replay, binary comparisons, regression gates, and integration tests. ChangesArchive benchmarking
Priority: ➖ Normal Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to This benchmark-only change improves performance measurement coverage, but Store encoder CPU results can be misleading when parallel workers are used. Remaining load-driver and error-reporting concerns should be resolved before relying on the harness for regression decisions. Sequence Diagram(s)sequenceDiagram

drive_requestspassestimeouttocollect, which labels a finished request as a timeout when its latency exceeds the budget. Nothing cancels the request. A stalled route future keeps its concurrency slot, and the drain loop at line 286 awaits it without a bound, so the harness hangs instead of reporting a timeout.Wrap the request future in

Summary
Implements the benchmark tooling from the revised archive-scale performance research plan (
plans/dolos-archive-scale-performance-research.mdin the planning repository).xtask/perf/README.md.Performance experiment organization
cargo xtask perf storage {run,node,train,evaluate}runs storage and corpus workloads.cargo xtask perf minibf {run,compare,http,check}runs actual minibf endpoint workloads and their regression gates.cargo xtask perf reportrenders either or mixed result records.xtask::perf::{storage,minibf}. Measurement, provenance, dictionary identity, the load driver and reporting are shared atxtask::perf; fixtures and store instrumentation remain indolos-testing.cargo bench; xtask integration tests are namedperf_cli,storage_perf_smoke, andminibf_perf.archive-benchstorage invocations remain compatible. Current guides live underxtask/perf/(overview, storage, minibf, HTTP); historical result paths are preserved.Validation
cargo +nightly-2026-08-27 fmt --all -- --checkcargo clippy --workspace --all-targets --all-features --offline— passes; seven pre-existing warnings in unchanged cardano/snapshot code, none in the added code.cargo build --workspace --all-targets --all-features --offlinecargo test --workspace --all-targets --offline— 1,482 passed, 48 ignored.cargo test --workspace --all-features --exclude dolos-minibf --exclude dolos-minikupo --exclude dolos-trp --offline— 1,020 passed, 53 ignored.The full validation suite was rerun after the storage/minibf split and the
perfrename. Two new CLI tests verify subject separation, legacy storage compatibility, paired child invocation through the new command tree, shared reporting and rejection of undersampled evidence.Documentation cleanup: replaced two overlapping guides with four concise task-oriented pages; checked 12 local links/anchors, 11 CLI examples, shell syntax, and the existing artifact privacy test. Runtime code and historical evidence are unchanged.
Scope and limitations
This adds regression tooling, not a mainnet performance verdict or production optimizations. Synthetic fixtures do not establish mainnet capacity. Real-node calibration is supported but was not run against mainnet. No redb archive comparison is restored, and no timing-sensitive CI gate is added.
