perfcapture

Capture the performance of a computer system whilst running a set of benchmark workloads. perfcapture is especially focused on benchmarking workloads which require a lot of IO.

Please note that perfcapture is a general-purpose benchmarking tool. Please see zarr-benchmark for Zarr-specific benchmarks. zarr-benchmark is built on top of perfcapture.

Features

• Easily to define new workloads and datasets.
• Orchestrate the creation of on-disk datasets (for benchmarking against).
• (TODO) Allow users to select workloads and datasets at the command line.
• (TODO) For each workload, measure a range of performance metrics including:
  • total runtime
  • total bytes of IO
  • total IO operations
• (TODO) Save performance metrics to disk as JSON.

Installation

1. Clone the repository.
2. Optionally create a virtual Python environment (e.g. with python -m venv </path/to/venv/>) and activate that venv (source </path/to/venv/>bin/activate).
3. pip install -e .

Usage

To run the examples:

~/dev/perfcapture$ mkdir -p ~/temp/perfcapture_data_path
~/dev/perfcapture$ python scripts/cli.py --data-path ~/temp/perfcapture_data_path --recipe-path examples
