Windows gaming latency analyzer: per-device input timing, CPU/GPU frames, DPC/ISR, scheduling, network, storage and audio. Passive kernel probe support.

Measure any tennis API against a published, reproducible method — response time, observed availability — and be told when your sample is too small to support a number.

Command-line benchmark for LLM APIs: send the same prompts to OpenAI and Anthropic models concurrently and compare p50/p99 latency, tokens per second, cost per request and success rate. Rust.
