AgentPerfBench
LLM inference benchmark: 3,392 serving runs, 148,077 per-kernel NCU profiles, and 4,715 latency predictions 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 (3,147 rows)
Replays exact ISL/OSL sequences from recorded agent sessions (SWE-Bench, TerminalBench, OSWorld, ShareGPT). 77 (model, hardware, engine) combinations, 17 profiles, 6 concurrency levels.
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
distributional (245 rows)
ISL/OSL sampled from lognormal fits to real workload statistics. 42 combinations, 6 profiles, 7 concurrency levels.
6 profiles: chat-multiturn, chat-singleturn, coding-singleturn, osworld-multiturn, swebench-multiturn, terminalbench-multiturn
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.
roofline_quadrant (2,163 rows)
Operational intensity and achieved throughput per kernel, for roofline analysis. H100 reference hardware (989 peak TFLOPS, 3.35 TB/s HBM).
predictions (4,715 rows)
Predicted vs. measured TTFT, TPOT, and E2EL for each serving configuration, with cache-aware prediction metadata. 14 hardware configs.
Concurrency filtering
Concurrency is controlled by a fixed-size connection pool. Trace replay uses levels {1, 5, 10, 20, 40, 80}; distributional uses {1, 5, 10, 40, 80, 200, 320}.
Early runs used a session-pool size smaller than the declared concurrency (num_sessions=100 for trace replay, num_sessions=10 for distributional), capping actual load below the nominal value. Rows where declared concurrency exceeded the session pool were dropped.
| Config | Rows |
|---|---|
| trace_replay | 3,147 |
| distributional | 245 |
| Total | 3,392 |

Loading
from datasets import load_dataset
ds = load_dataset("agent-perf-bench/AgentPerfBench", "trace_replay")
# or "distributional", "kernels_labeled", "roofline_quadrant", "predictions"
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.
