DOWNLOAD CLIENT SWEEP · WEAVER 0.13.4
Every client gets the same NZB, the same shaped link, and the same transport, inside the same measurement block. The sequential-run clock starts at submission and stops only once the client reports a terminal state and the harness has verified the output bytes.
Headline comparisons on Linux x86_64 (Docker). Wall figures express the speedup over Weaver; CPU figures compare total processor time used to finish the work.
| SCENARIO | VS. SABnzbd WALL SPEEDUP | CPU TIME | VS. NZBGet WALL SPEEDUP | CPU TIME |
|---|---|---|---|---|
| Common Usenet postings 1 Gbit/s link at 10 ms and 100 ms RTT*, TLS and plaintext, every fixture in the corpus (phases B3 and P3, both RTTs, geometric mean over all compared strata) | 51.3% faster | 57.0% less | 123.7% faster | 46.9% less |
| Unthrottled 10 Gbit/s · 0 ms RTT* · TLS. 10 copies of the 200 MB direct download, queued at once. Queue-drain clock; verification completes afterward. | 72.5% faster | 45.8% less | 277.6% faster | 82.6% less |
| Edge cases The subset of the Usenet standard strata whose fixture is a compressed RAR or 7z, a quick-open RAR, or needs PAR2 or recovery-volume repair | 49.3% faster | 51.8% less | 128.4% faster | 41.1% less |
* RTT (round-trip time) is the time a request takes to travel to the server and a response to travel back, measured in milliseconds. Higher RTT means more network delay; 100 ms is one tenth of a second. On higher-latency real-world connections, RTT can range from 100 ms to over 1 second. Here, RTT is controlled by the benchmark’s network shaper.
“Faster” = (baseline wall time ÷ Weaver wall time − 1) × 100. Standard and edge-case figures use geometric means over compared strata. The unthrottled headline uses the dedicated queue-drain run with CPU accounting.
Each client runs the way its users install it. A shaped NNTP server on the same host keeps provider variance out of the comparison.

shaped NNTP server on the same host (loopback), shaper sets link rate and RTT
CPU accounting: client process tree job cycle time (nominal 3600 MHz).
rigs are named by CPU architecture, operating system, and how the clients ran (container or native); no machine identities are recorded
Median wall time from submission to verified output. Shorter is better. Explore the rigs, transports, link conditions, and storage profiles; each selection includes its phase aggregates and paired measurements.

Charts show one representative fixture per label, using the first matching fixture in the source data. Full measurements remain available below. Shorter is better. Each pane uses its own time scale; compare the labeled times across panes. Small hatched markers indicate DNF (did not finish), with no measured duration. N/A means too few paired results. Both are excluded from speedup figures.

Charts show one representative fixture per label, using the first matching fixture in the source data. Full measurements remain available below. Shorter is better. Each pane uses its own time scale; compare the labeled times across panes. Small hatched markers indicate DNF (did not finish), with no measured duration. N/A means too few paired results. Both are excluded from speedup figures.

Speedup = baseline wall time ÷ Weaver wall time. Above 1× favors Weaver; below 1× favors the baseline. Phase figures are geometric means of paired comparisons.

Charts show one representative fixture per label, using the first matching fixture in the source data. Full measurements remain available below. Shorter is better. Each pane uses its own time scale; compare the labeled times across panes. Small hatched markers indicate DNF (did not finish), with no measured duration. N/A means too few paired results. Both are excluded from speedup figures.

Speedup = baseline wall time ÷ Weaver wall time. Above 1× favors Weaver; below 1× favors the baseline. Phase figures are geometric means of paired comparisons.

Charts show one representative fixture per label, using the first matching fixture in the source data. Full measurements remain available below. Shorter is better. Each pane uses its own time scale; compare the labeled times across panes. Small hatched markers indicate DNF (did not finish), with no measured duration. N/A means too few paired results. Both are excluded from speedup figures.

Charts show one representative fixture per label, using the first matching fixture in the source data. Full measurements remain available below. Shorter is better. Each pane uses its own time scale; compare the labeled times across panes. Small hatched markers indicate DNF (did not finish), with no measured duration. N/A means too few paired results. Both are excluded from speedup figures.

Charts show one representative fixture per label, using the first matching fixture in the source data. Full measurements remain available below. Shorter is better. Each pane uses its own time scale; compare the labeled times across panes. Small hatched markers indicate DNF (did not finish), with no measured duration. N/A means too few paired results. Both are excluded from speedup figures.

Speedup = baseline wall time ÷ Weaver wall time. Above 1× favors Weaver; below 1× favors the baseline. Phase figures are geometric means of paired comparisons.

The homepage queue race uses the dedicated CPU-accounted run. The JSON reports queue drain and verified output separately; these are the recorded clocks for that same run.

The benchmark measures a complete download pipeline. Equivalent-throughput phases tune each client for the same link; the stock-settings and network-storage phases remain separately selectable.

Exact performance varies with hardware, providers, and archive shape. Results withheld for insufficient paired blocks are excluded from speedups. The raw data includes build identifiers, per-fixture confidence intervals, CPU seconds, and downstream byte counts.
