speedrunner

The speedrunner project provides a significant performance enhancement for various command-line tools, including AWS, Azure, Google Cloud, Ansible, eslint, rubocop, composer, and many others developed in Python, Ruby, PHP, and Node.js. By leveraging a daemon architecture, speedrunner remains loaded in memory, allowing tools to start up to 10 times faster by avoiding the interpreter startup overhead.

Key Features

• Performance Enhancement: Speedrunner allows hundreds of command-line tools to execute dramatically faster. Benchmarks show that a series of checks took 24.0 seconds natively but completed in just 5.3 seconds using speedrunner exec, resulting in an impressive speedup of approximately 4.5 times.
• Simple Setup: No complex configuration is required for individual tools. Speedrunner works with a single binary for ease of use on both Linux and macOS platforms.
• Real-Time Execution: Commands are processed by preloaded daemons that fork for each call, which significantly reduces latency during execution.

Usage Example

Users can effortlessly run commands without additional setup:

srr aws s3 ls  # Executes any supported tool with speedrunner
speedrunner exec ./script.sh  # Runs a whole script with all tools preloaded
eval "$(speedrunner activate)"  # Initialize in scripts without additional prefixes
speedrunner enroll aws  # Enables plain usage in zsh or bash

Performance Demonstrations

• Script Checks: A bash script running various checks (like black and pytest) demonstrated a drop from 24.0 seconds to 5.3 seconds, maintaining the same output.
• File Editing: Running eslint on a single file reduced execution time from 328 milliseconds to just 43 milliseconds, outperforming the tool's own daemon.
• Version Control: The speedrunner exec command can be integrated with git operations to enhance commit speeds while maintaining identical output.

Benefits of Using Speedrunner

• Compatibility: Works seamlessly with a broad range of popular command-line tools, resulting in a unified user experience without tool-specific configurations.
• Efficient Resource Management: After the initial call, subsequent usages become significantly faster. In addition, each daemon can be configured to shut down after a period of inactivity, thus managing system resources efficiently.
