This document discusses benchmarking at Euro-IX, an association of internet exchange points (IXPs). It describes how Euro-IX operates a voluntary Benchmarking Club (BMC) to allow IXPs to anonymously share and compare operational data to identify best practices and areas for improvement. The BMC survey is conducted annually, with participation increasing over time. Categories of data shared include prices, traffic metrics, financial performance, and staffing. Benchmarking is intended to help IXPs look outward and learn from one another's experiences.
