CPU Benchmark - single core speed test with Fibonacci Sequence in JavaScript

In this short article, I would like to show Fibonacci Sequence test that is run on a single core. The test source code was converted from C++ to JavaScript - check source article.

Example test.js file:

let tmp, a = 0, b = 1;

console.log('Started!');
  
const t1 = Date.now();

for (let i = 0; i < 10000; ++i) {
  	for (let j = 0; j < 1000000; ++j) {
      	tmp = b;
        b = a + b;
        a = tmp;
    }
}

const t2 = Date.now();
const dt = t2 - t1;

console.log('Finished!');

console.log(`Result: ${b}`);
console.log(`Time: ${0.001 * dt}s`);

Running with Node.js:

node test.js

Example output:

Started!
Finished!
Result: Infinity
Time: 17.531s

Notes: Result: Infinity printing is used only to prevent against automatic optimization.

Used Node.js: v14.16.0

Used OS: Windows 10 x64

Used PC:

• Ryzen 9 5900x
• DRR 4 (2x 32GB)
• Samsung SSD M.2 970 EVO (1TB)
• GeForce GTX 970 (4GB RAM)

Notes:

• same test for the first run under Node.js v16.13.0 took 18.430s,
• same test run few times under same Node.js instance returned 6.110s - V8 made some optimisation.
