Hello,
I was curious if anyone's experimented with how fast node.js and socket.io
are capable of sending out data.
I know there's benchmarks on number of connections and stuff like that but
I'm talking for a single connection, maximum connection rate.
Suspecting this would be very dependent on server hardware.
I'm expirementing with creating a speedtest using Node.js through a
websocket. Presently I'm able to achieve consitantly reach speeds of
100Mbps with random spikes into ~120Mbps range using fs.createReadStream
on a text file and sending the data to a browser.
Has anyone else seen anything like this or know of something that perhaps
would be faster?
Here's my server code. I've tried messing with the bufferSize up / down
but it really didnt have any affect.
I've also tried various browsers on a range of machines all with
connections of 1Gbps.
var io = require('socket.io').listen(81);
var fs = require('fs');
var readStream = fs.createReadStream("output.txt",
{'flags': 'r',
'encoding': 'binary',
'mode': 0666,
'bufferSize': 64 * 1024});
io.sockets.on('connection', function (socket) {
readStream.on('data', function(data) {
socket.send(data);
});
});
