Benchmark workloads and evaluation results live in a dedicated companion repo: https://github.com/onlyxItachi/PerfDigest-MCP-Bench — keeping large report artifacts and result documents out of this code repo. Unit tests stay here (they gate CI); only benchmark/eval artifacts moved.
Headline results measured so far:
- Token efficiency: the digest costs ~14–130x fewer tokens per turn than raw
ncuoutput for the same correct diagnosis — results/RESULTS.md. - Cross-backend, real hardware: NVIDIA (
nsight) and CPU (linux_perf) digests validated on a real RTX 4060 + Ryzen host through one MCP call shape — results/CROSS_BACKEND_2026-06-15.md.
To reproduce, see workloads/README.md in the bench repo (capture commands for both workloads).
