# AgentPerfBench

LLM inference benchmark: 3,197 main sweep rows and 37 per-layer kernel validation rows, plus 148,077 per-kernel NCU profiles, across 9 models, 14 GPU configurations, and 2 serving engines (vLLM 0.19.0, SGLang 0.5.9). All models served in BF16 except gpt-oss, which uses mxfp4 for projection weights.

## Dataset configurations

### trace_replay (2,932 rows)

Replays exact ISL/OSL sequences from recorded agent sessions (SWE-Bench, TerminalBench, OSWorld, ShareGPT). 77 unique (model, hardware, engine) combinations across 17 profiles.

17 profiles: `chat-medium`, `chat-multiturn-long`, `chat-multiturn-medium`, `chat-multiturn-short`, `chat-short`, `chat-singleturn`, `coding-singleturn`, `decode-heavy`, `osworld-multiturn-long`, `osworld-multiturn-medium`, `osworld-multiturn-short`, `prefill-heavy`, `random-1k`, `swebench-multiturn-medium`, `swebench-multiturn-short`, `terminalbench-multiturn-medium`, `terminalbench-multiturn-short`

### synthetic_distributional (265 rows)

ISL/OSL sampled from lognormal fits to real workload statistics. 38 unique (model, hardware, engine) combinations across 5 profiles.

5 profiles: `chat-multiturn-synth`, `chat-singleturn-synth`, `osworld-multiturn-synth`, `swebench-multiturn-synth`, `terminalbench-multiturn-synth`

### per_layer_kernel (37 rows)

Per-component operational intensity decomposition and Nsight Compute kernel profiles for Llama-3.1-8B on H100 (prefill phase). Analytical rows provide computed FLOPs, bytes, and OI per model component at batch sizes 1 and 80. NCU rows report measured SM and memory throughput per kernel from an 8-layer forward pass. Record types: `analytical_total`, `analytical_component`, `ncu_kernel`.

### kernels_labeled (148,077 rows)

Per-kernel Nsight Compute (ncu) profiles across 4 GPUs (A100, H100, RTX 3090, RTX 2080 Ti) and 13 model/sweep sources.

### mse_validation (28 rows)

Curated H100 / Llama-3.1-8B / vLLM validation table for the distributional synthetic replay generator. Paired synthetic and real trace replay runs; supplementary rows preserve no-replacement and high-concurrency debug runs. Raw JSON artifacts referenced through R2 URI columns. Per-run successful/failed request counts retained.

### Quality filtering

Configurations where fewer than 75% of requests completed successfully are excluded. Summary metrics are computed from successful requests only.

| Config | Rows |
|--------|------|
| trace_replay | 2,932 |
| synthetic_distributional | 265 |
| per_layer_kernel | 37 |
| kernels_labeled | 148,077 |
| mse_validation | 28 |

## Loading

```python
from datasets import load_dataset

ds = load_dataset("agent-perf-bench/AgentPerfBench", "trace_replay")
# or "synthetic_distributional", "per_layer_kernel", "kernels_labeled", "mse_validation"
```

## Benchmark methodology

- Closed-loop concurrency with semaphore control.
- 3-request warmup before each configuration.
- Metrics: TTFT, TPOT, ITL, E2EL, request throughput, token throughput (mean, median, p90, p99).
- Metrics computed over successful requests only.
- Collection period: March 2026 onwards.

## Limitations

- Distributional profiles are fitted approximations, not direct production replays.
- Closed-loop concurrency only; no open-loop (Poisson) arrivals.

## Ethical considerations

No PII. Trace-replay profiles derive from open benchmarks (SWE-Bench MIT, TerminalBench, OSWorld). Synthetic profiles use random tokens.
