Included review availability: Your plan includes up to 3 reviews per rolling hour; 1 remains after this review. 📝 WalkthroughWalkthroughChangesThe benchmark runner now executes multiple scenarios, supports containerized client network shaping, archives per-scenario results, and builds Linux clients. Scenario files add local, mainnet, and testnet configurations. Benchmark metrics now track transaction counts. Benchmark tooling
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The batch runner can report success when an individual benchmark fails, and the configured network shaping may not measure the documented RTT and total-bandwidth conditions, making automation status and benchmark results misleading. These bounded issues should be corrected or explicitly accepted before relying on the benchmarks. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@dash-spv-bench/run.sh`:
- Around line 133-147: Update the scenario execution loop around the BENCH_BATCH
pipeline to capture the child benchmark’s exit status immediately via PIPESTATUS
before subsequent commands overwrite it. Add that status as a column in each TSV
scenario record, track whether any scenario failed, and return a nonzero status
after all scenarios complete if at least one child failed.
- Around line 322-324: Update dash-spv-bench/run.sh lines 322-324 to configure
an IFB device for ingress and apply the same NETEM_ARGS policy to both ingress
and egress, preserving the existing warning behavior. Update
dash-spv-bench/scenario.example.yml lines 14-22 to document bidirectional
shaping semantics. Retain and validate the stated RTT claims in
dash-spv-bench/scenarios/mainnet.50mbi.100ms.yml lines 10-12,
dash-spv-bench/scenarios/mainnet.50mbi.500ms.yml lines 10-12,
dash-spv-bench/scenarios/mainnet.8mbi.1000ms.yml lines 10-12,
dash-spv-bench/scenarios/mainnet.8mbi.100ms.yml lines 10-12, and
dash-spv-bench/scenarios/mainnet.8mbi.500ms.yml lines 10-12 once both directions
are shaped.
In `@dash-spv-bench/scenarios/local.1ideal.yml`:
- Around line 7-11: Revise the shared scenario notes to accurately describe
which settings are uniform: in dash-spv-bench/scenarios/local.1ideal.yml lines
7-11, local.1slow-2ideal.yml lines 8-12, local.3ideal.yml lines 7-11, and
local.5ideal.yml lines 7-11, state that only client-link network settings are
uniform; in local.5slow-congested.yml lines 7-11, account for the differing CPU
allocation; and in local.8slow.yml lines 13-17, account for differing CPU,
peer-limit, repeat, and block settings.
In `@dash-spv-bench/src/metrics.rs`:
- Around line 150-157: Add unit tests for the transaction-tracking logic in the
nearest metrics test module, covering that a lower count after a higher count
does not reduce the stored maximum, snapshot() returns the stored transaction
count, and formatted output includes the transactions field. Reuse the existing
metrics/progress construction and assertion patterns rather than changing the
implementation.
- Around line 150-157: Synchronize or flush the progress monitor before
signaling completion so the final on_progress update is processed before
wait_done() returns and snapshot() reads metrics. Update the completion path
around on_sync_event/SyncComplete to wait for monitor shutdown or an equivalent
barrier, while preserving the existing highest-count aggregation in the progress
callback.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Shape ingress traffic before reporting RTT and total bandwidth.
tc qdisc add dev eth0 root netem shapes only client egress. It delays outbound packets and caps upload traffic. It does not delay inbound peer responses or cap block and filter downloads. The reported RTT is therefore not 2 * latency_ms, and rate_kbit is not the client’s total bandwidth.
