Description: As in other places, we don't need to call Buffer.alloc(0), which validates the length and calls FastBuffer anyway, when we're creating an empty Buffer This bypasses the validation logic and is consequently faster buffers/fast-buffer.js buffers/fast-buffer.js operation="fastbuffer" n=1000000: 47,834,970.118450865 buffers/fast-buffer.js operation="bufferalloc" n=1000000: 33,173,868.757805813 'use strict'; // flags: --expose-internals const common = require('../common'); const { FastBuffer } = require('internal/buffer'); const bench = common.createBenchmark(main, { n: [1e6], operation: ['fastbuffer', 'bufferalloc'], }); function main({ n, operation }) { switch (operation) { case 'fastbuffer': bench.start(); for (let i = 0; i < n; i++) { new FastBuffer() } bench.end(n); break; case 'bufferalloc': bench.start(); for (let i = 0; i < n; i++) { Buffer.alloc(0) } bench.end(n); break; } }
