Jamf Protect + Node.js Fork Performance Benchmark

This project contains a script that measures how long it takes tinypool to fork 50 Node.js worker processes that each log a message to the console.

Usage

  1. Either clone or download this repository to your local machine.

  2. Ensure that you have a recent LTS version of Node.js installed. This project was tested with Node.js 20.17.0.

  3. In the project directory, run npm install to install dependencies.

  4. Run npm start to run the benchmark.

Output

The script will print a message as each worker process starts. After all processes have started, the script will report the total time taken to fork all worker processes.

On a 2021 MacBook Pro with an M1 Pro processor, Node.js 20.17.0 typically finishes the benchmark in ~250 milliseconds when Jamf Protect is not enabled. With both Jamf Protect and BlockBlock <=2.2.3 enabled, the benchmark finishes in ~30 seconds.

Note

This issue is fixed in BlockBlock 2.2.4!
