Websocket ping performance cocos2d-js android

cocos2d-x JavaScript
#1

Hello guys.

I have simple echo server (nodejs). And cocos2d-js application that measures ping time.

Here is results for different platforms:
Web ~ 1-2ms
Android ~ 70-250ms

I run this test using home wi-fi router (no internet data transfer).

Why ping on android is so huge? How can I achieve 1-2ms?

Thanks in advance :slight_smile:

I found this also using websockets on android sending data every update crashes sometimes on android but is fine on desktop and ios devices

I have similar problem. That’s another thing to investigate. Maybe we should report this strange behavior to issue tracker?

Yes i suppose so but im assuming they know about it??
The only way around it on android is to slow down the updates by a huge amount.
Really irritating though!

@samuele3hu is taking charge of network libraries of Cocos2d, can you check this issue ?

Can you give me the test codes,thanks.

I dont have any test codes!
But on android if you use websockets to send a message every update loop it will run then crash after a few seconds when it gets overloaded.
If you delay and only send one message every 8 loops it runs fine.
This was my issue anyway but on ios devices its perfect and able to handle constantly sending messages

Hello @samuele3hu, sorry for the delay.

Client:

var socket = new WebSocket("ws://192.168.88.226:8899"), time;

console.log('Started');
function ping() {
    time = new Date().getTime();
    console.log('Ping sent!');
    socket.send('ping');
}

socket.onmessage = function (event) {
    console.log('Ping is ' + (new Date().getTime() - time));
    setTimeout(ping, 1000);
};

setTimeout(ping, 1000);

Server:

var WebSocketServer = require('ws').Server,
    socket = new WebSocketServer({port: 8899});

console.log('Started!');

socket.on('connection', function (clientSocket) {
    clientSocket.on('message', function () {
        console.log('Ping!');
        clientSocket.send('pong');
    });

    console.log('Connected!');
});

On andriod ping value is 70-250ms :smile: On web 1-2ms
Changing client code to:

var socket = new WebSocket("ws://192.168.88.226:8899"), time, count;

console.log('Started');
function ping() {
    time = new Date().getTime();
    console.log('Ping sent!');
    socket.send('ping');
}

count = 5000;
while (count--) {
    ping();
}

Fatal signal 11 (SIGSEGV), code 1, fault addr 0x4 in tid 4891 (GLThread 4804)
Take a look at screenshot: http://joxi.ru/Y82QzP5twZMwAd
I tested it with android-ndk-r9d, cocos 3.0 and 3.1, LG-Nexus 5
