# Comet Benchmarking Guide

To track progress on performance, we regularly run benchmarks derived from TPC-H and TPC-DS.

The benchmarking scripts are contained [here](https://github.com/apache/datafusion-comet/tree/main/benchmarks/tpc).

Data generation scripts are available in the [DataFusion Benchmarks](https://github.com/apache/datafusion-benchmarks) GitHub repository.

## Current Benchmark Results

The published benchmarks are performed on a Linux workstation with PCIe 5, AMD 7950X CPU (16 cores), 128 GB RAM, and
data stored locally in Parquet format on NVMe storage. Performance characteristics will vary in different environments
and we encourage you to run these benchmarks in your own environments.

The operating system used was Ubuntu 22.04.5 LTS.

## Benchmarking Guides

Available benchmarking guides:

- [Benchmarking on macOS](benchmarking_macos.md)
- [Benchmarking on AWS EC2](benchmarking_aws_ec2)
- [TPC-DS Benchmarking with spark-sql-perf](benchmarking_spark_sql_perf.md)

We also have many micro benchmarks that can be run from an IDE located [here](https://github.com/apache/datafusion-comet/tree/main/spark/src/test/scala/org/apache/spark/sql/benchmark).
