You can find setup and usage instructions in the [Profiling Guide](docs/PROFILING.md). Profiling can help identify performance bottlenecks in block processing, transaction validation, and EVM execution. Please ensure the profiler is run as the same user that started the Besu process. ## Release Notes [Release Notes](CHANGELOG.md) ## Reference Tests and JSON Tracing Besu includes support for running Ethereum reference tests and generating detailed EVM execution traces. To learn how to run the tests and enable opcode-level JSON tracing for debugging and correctness verification, see the [Reference Test Execution and Tracing Guide](REFERENCE_TESTS.md).
