# Sparse Retrieval Efficiency on MSMARCO v1 (test) Source: [Sparse Retrieval Efficiency on MSMARCO v1 (test)]() Collection index: [llms.txt]() Data updated: 2026-02-27T11:52:14.660Z Evaluation of Sparse Retrieval system efficiency on the MSMARCO v1 test set, reporting detailed latency percentiles (e.g., @99 accuracy) and index size. A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Sparse Retrieval Efficiency | | Dataset (including any stated split) | MSMARCO v1 (test) | | Metric | Latency @ 90% Acc (µs) | | Unit | TIME | | Direction | Lower is better | | Results loaded | 16 of 16 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [Latency @ 90% Acc (µs)](): Lower is better; unit: TIME. - [Latency @ 95% Acc (µs)](): Lower is better; unit: TIME. - [Latency @ 97% Acc (µs)](): Lower is better; unit: TIME. - [Latency @ 99% Acc (µs)](): Lower is better; unit: TIME. - [Index Size (GB)](): Lower is better; unit: SIZE. ## Recorded results | Method | Latency @ 90% Acc (µs) | Result date | Report paper | | --- | --- | --- | --- | | DotVByte | 156 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | Uncompressed | 157 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | DotVByte | 165 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | Uncompressed | 185 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | StreamVByte | 402 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | StreamVByte | 425 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | Uncompressed | 518 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | DotVByte | 529 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | DotVByte | 662 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | Uncompressed | 670 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | Zeta | 825 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | Zeta | 848 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | StreamVByte | 2019 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | StreamVByte | 2386 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | Zeta | 8220 | Not recorded | 6985758ac97a0b3e3b5d5c72 | | Zeta | 11363 | Not recorded | 6985758ac97a0b3e3b5d5c72 | ### DotVByte Latency @ 90% Acc (µs): 156.
