This repo tests the nanosecond precision of process.hrtime() inside of an infinite while loop.
There is a noticeable delta (~0.2 ms) per loop caused by calculations and logging to the console.
The delay depends on your CPU speed, the example below was done on a Ryzen 9 3900X.
Make sure you have node.js installed on your system.
Clone the repository and run this command inside the project folder.
