О чём код?
// Test UDP send/recv throughput with the "old" offset/length API 'use strict'; const common = require('../common.js'); const dgram = require('dgram'); const PORT = common.PORT; // `n` is the number of send requests to queue up each time. // Keep it reasonably high (>10) otherwise you're benchmarking the speed of // event loop cycles more than anything else. const bench = common.createBenchmark(main, { len: [1, 512, 1024], n: [100], type: ['send', 'recv'], dur: [5], }); function main({ dur, len, n, type }) { const chunk = Buffer.allocUnsafe(len); let sent = 0; let received = 0; const socket = dgram.createSocket('udp4'); function onsend() { if (sent++ % n === 0) { // The setImmediate() is necessary to have event loop progress on OSes // that only perform synchronous I/O on nonblocking UDP sockets. setImmediate(() => { for (let i = 0; i < n; i++) { socket.send(chunk, 0, chunk.length, PORT, '127.0.0.1', onsend); } }); } } socket.on('listening', () => { bench.start(); onsend(); setTimeout(() => { const bytes = (type === 'send' ? sent : received) * chunk.length; const gbits = (bytes * 8) / (1024 * 1024 * 1024); bench.end(gbits); process.exit(0); }, dur * 1000); }); socket.on('message', () => { received++; }); socket.bind(PORT); }
