llmperf-rs ships lightweight LLM benchmarking

llmperf-rs is a Rust-based CLI for quickly measuring LLM token throughput and latency against OpenAI-compatible endpoints such as vLLM and llama.cpp. The project positions itself as a simpler, single-binary alternative to heavier benchmark suites like Ray's archived llmperf, GuideLLM, aiperf, and vLLM bench.

// ANALYSIS

The useful angle here is restraint: llmperf-rs is not trying to become a full eval platform, just a fast sanity-check tool for inference performance.

–Single-binary distribution lowers friction for server operators who want quick latency and throughput checks without a benchmark environment
–OpenAI-compatible endpoint support makes it practical for local and hosted inference stacks, especially vLLM-style deployments
–Optional PostgreSQL reporting gives teams a path from one-off tests to historical tracking without forcing that complexity upfront
–The risk is scope creep: benchmarking tools get messy fast once users ask for datasets, warmups, non-streaming modes, concurrency profiles, and provider-specific quirks
