Readme
This is a small utility that supports:
async
functions (on top of simple synchronous functions).abort()
in order to, well, abort!.add(name, function)
).add(name, { prepare, unit, teardown })
).setWarmupTime(milliseconds)
).setMaxUnitTime(milliseconds)
).setRunsPerUnit(runs)
)await benchmark.run(options)
for compatibility with modern await
syntax or .then
/.catch
npm i benchmark-util
(async () => {
const Benchmark = require('benchmark-util');
let bench = new Benchmark();
bench
.add(`Test performance of tiger`, () => {
/running tiger/.test('Find a running tiger in this string');
})
.add(`Test performance of async tigers`, (() => {
async function lookForRunningTiger() {
return /running tiger/.test('Find a running tiger in this string');
}
return async () => {
await lookForRunningTiger();
};
})())
.add(`Test performance of async tigers with Promise`, async () => {
await new Promise(resolve => {
resolve(/running tiger/.test('Find a running tiger in this string'));
});
})
.add(`Test with prepare & teardown`, {
prepare: () => console.log('This is me preparing'),
unit: () => {
/running tiger/.test('Find a running tiger in this string');
},
teardown: () => console.log('This is me tearing it down'),
});
let results = await bench.run({
onCycle: ({ name, totals, samples, warmup }) => {
console.log(`${name} x ${Math.round(totals.avg)} ops/sec ± ${Math.round((totals.stdDev / totals.avg) * 10000) / 100}% (${totals.runs} runs sampled)`);
}
});
let fastest = results.sort((a, b) => a.totals.avg > b.totals.avg ? -1 : a.totals.avg < b.totals.avg ? 1 : 0)[0].name;
console.log(`Fastest is: ${fastest}`);
})();
