Lanbench May 2026

Create a benchmark.yaml file:

server:
  url: "http://192.168.1.100:8000/v1/completions"
  api_key: "your-key-if-any"
  timeout_seconds: 120
scenarios:
Let's walk through a practical example. Assume you have deployed an LLM server at 192.168.1.100:8000 and want to benchmark its true LAN performance. LANBench
LANBench is a simple, open-source tool that allows users to benchmark their network's performance. It does this by transferring large files over the network between two computers and measuring the throughput.
LANBench is not just a testing tool; it is a diagnostic scalpel for AI engineers. Create a  benchmark
LANBench is an essential tool for several network management tasks:
The process typically involves:
How does LANBench stack up against the competition?
| Tool | Focus | Network Aware? | Concurrency? | Best For |
| :--- | :--- | :--- | :--- | :--- |
| LM Evaluation Harness | Accuracy (MMLU, HellaSwag) | No | No | Model capability |
| llama-bench | CPU/GPU compute speed | No | No | Hardware optimization |
| Artillery / k6 | General HTTP load | Yes | Yes | Not AI-native (no token streaming metrics) |
| LANBench | LLM-specific LAN perf | Yes | Yes | Production AI servers | It does this by transferring large files over
While designed for LANs, it is frequently used to test Wi-Fi performance under controlled conditions. By moving a laptop around a building and running LANBench against a wired server, administrators can map out wireless dead zones based on throughput degradation.
