newJS Posted September 17, 2019 Share Posted September 17, 2019 I'm trying to read data from the file as follows and send data to the client. I can send a 20MB file in 30 seconds. But I have to send 20MB per second. Am I doing something wrong? [Server.js] var File = require('File') var FileReader = require('filereader'), fileReader = new FileReader(); fileReader.setNodeChunkedEncoding(true || false); fileReader.readAsArrayBuffer(new File('../Test.txt')); fileReader.addEventListener('load', function (ev) { JsonData = JSON.stringify(new Int16Array(ev.target.result);); }); var app = require('express')(); var http = require('http').createServer(app); var io = require('socket.io')(http); io.on('connection', function(socket){ console.log('a user connected'); console.log("DateTime : " + getDateTime()); socket.on("update", function(data){ console.log("DateTime : " + getDateTime()); socket.send(JsonData); }); socket.send(JsonData); socket.on('message', function(msg){ console.log('message: ' + msg); }); socket.on('disconnect', function(){ console.log('user disconnected'); }); }); http.listen(9099, function(){ console.log('listening on *:9099'); }); [Client.js] var socket = io("http://localhost:9099"); socket.on('message', function(message) { var JsonData = JSON.parse(message); socket.emit("update", { data:"getData"}); }); Socket.io version : 2.2.0 Filereader version: 0.10.3 NodeJS version: 10.16.3 Quote Link to comment Share on other sites More sharing options...
